Now, according to the mirror formula, we know that: 1/f = 1/v - 1/u Now, by substituting the given data, we get: 1/12 = 1/v - 1/18 Solving for v, we get: v = 36 cm ii) In order to determine the height of an image, we need to use the magnification formula: m = -v/u m = -36/18 = -2 Thus, the image is twice as big as the object but inverted. h' = -2 x 3 cm = -6 cm

A rapid revision of the chapter on light covers key concepts such as reflection, properties of mirrors, and the behavior of light through lenses. It emphasizes important laws, formulas, and practical applications, including how to solve numerical problems. The session aims to clarify complex topics efficiently for Class 10 students. ##### You may be interested in these questions: - [What are the main properties of light?](#related) - [How do concave and convex mirrors differ?](#related) - [What is the significance of the focal length in lenses?](#related) Highlights: 00:04 Light is a significant chapter in physics that involves understanding its properties and behavior. This revision covers essential concepts such as reflection, plane mirrors, and spherical mirrors. -The reflection of light occurs when it bounces off a shiny surface, following specific laws that govern its behavior. Understanding these laws is crucial for solving related numerical problems. -Plane mirrors produce virtual and erect images, and their properties include lateral inversion and equal size of the image compared to the object. This understanding is vital for practical applications. -Spherical mirrors, including concave and convex types, have unique characteristics that affect how they reflect light. Recognizing their differences helps in comprehending various optical phenomena. 04:04 The focal length is the distance from the pole to the focus of a mirror, which plays a crucial role in the behavior of light rays. Understanding properties of concave and convex mirrors helps in predicting how light interacts with them. -Light rays that pass through the focus of a concave mirror will emerge parallel, illustrating the converging nature of these mirrors. This property is essential for understanding image formation. -The center of curvature for both concave and convex mirrors reflects light rays back along the same path. This fundamental property is key for various optical applications. -A practical trick for remembering the image formation positions in concave mirrors involves identifying focal points. This aids in predicting where images will be formed based on the object's location. 08:08 Understanding image formation in mirrors is crucial for mastering optics. The nature of the image-whether real or virtual-depends significantly on the object's position relative to the mirror. -The relationship between the object's position and image type is essential. When an object is between the focus and the pole, a virtual and erect image is produced. -Concave mirrors are primarily used to enlarge images, making them valuable in applications like torches and makeup mirrors. Their ability to create real images is also noteworthy. -Conversely, convex mirrors create smaller images and are commonly used in car side mirrors and shaving mirrors. They provide a wider field of view, enhancing safety. 12:11 Understanding the rules of sign convention is essential for solving mirror-related problems in optics. Accurate application of these rules leads to correct calculations of focal length, image distance, and magnification. -The mirror formula, represented as 1/v + 1/u = 1/f, is vital for finding relationships between object distance, image distance, and focal length. This formula relies heavily on correct sign conventions. -Magnification is defined as the ratio of the height of the image to the height of the object. The formula m = -v/u helps determine whether the image is real or virtual. -Refraction describes how light bends when passing from one medium to another. Snell's Law governs this bending, establishing the relationship between angles of incidence and refraction. 16:14 The refractive index of a medium determines how much light bends when passing through it, with higher indices indicating greater bending. Understanding this concept is crucial for studying optics and light behavior. -The difference between rarer and denser media influences light behavior, as light bends towards the normal when moving from a rarer to a denser medium. This principle is essential in optics. -The formula for calculating refractive index is derived from the ratio of the speed of light in air to that in the medium. This relationship highlights the inverse nature of refractive index and light speed. -Understanding lens types, such as convex and concave, is vital for grasping how light focuses or diverges. Their unique properties determine how images are formed in optical systems. 20:16 Light passing through the optical center of a lens travels in a straight line, following three fundamental rules. Understanding these rules is essential for analyzing ray diagrams of convex and concave lenses. -The ray diagram techniques for both convex and concave lenses are similar to those used in mirrors, making the transition easier for learners. It's important to follow the same numbering method in both diagrams. -Understanding the formation of images based on object positions relative to the focal points is crucial. Various cases illustrate how images can be real or virtual depending on the object's location. -The applications of convex and concave lenses differ, with convex lenses used in magnifying glasses and concave lenses in telescopes. Each type serves specific purposes in optics. 24:20 The focal length of a convex lens is always positive, while that of a concave lens is negative. This distinction is crucial for understanding lens power and image formation. -Understanding the sign convention for focal lengths is essential. Convex lenses have positive focal lengths, while concave lenses have negative ones, affecting calculations. -The power of a lens indicates its ability to converge or diverge light. Positive power corresponds to convex lenses, and negative power to concave lenses. -When calculating power using the formula P = 1/f, ensure focal length is in meters. Converting centimeters incorrectly can lead to wrong answers.

Formulas related to reflection of light, => in reflection angle of incidence is equal to angle of relection, magnification = height of image/height of object m=hi/ho wher m is the magnification hi is the height of image ho is the height of object =>also m=-v/u formulaes related to refraction of light, => n =sini/sinr where n is the refractive index i is angle of incidence r angle of refraction =>lens formula 1/f =1/v -1/u =>power of lens,p=1/f(in m ) p=100/f(in cm) =>power of combination of lens P=P1+P2+P3... =>magnification ,m=hi/ho m=v/u => refractive index n21=speed of light in medium one /speed of light in medium 2 n21=v1/v2

Aby one from barabanki 3:53

[@RajShekhar-hw1bl]

Yes

[@BhawanjotKaur-h8l]

h=3cm F=-12cm U=-18cm Now, using Mirror formula 1\u +1/v = 1/f, 1/-18 +1/v =1/f 1/v=1/-12+ 1/18 1/v=-3+2/36 1/v=-1/36 V=-36 Now, m=-v/u m=-(-36)/-18 m=-2 Again, m=h'\h -2=h'/3 -2×3=h' -6=h' h'=-6 Therefore, distance of the image from the mirror is 36cm. Height of the image is 6cm. Now, Answer= -36/-6. Therefore, option (b) is correct Answer.
