Answer- we can see animals withput light as they are non luminious objects by the light that is coming from objects that are luminious reflects the colours of animals
I have a doubt... Agar ek object ko phele se hi upside down krke rakha hua ho to concave mirror ki wajah se screen me woh object ka image seedha aayega kya ?? And jo movies screen me dekhte hain hum wo kya phele se hi undide down hota hai projector me ??? Jisse hi hame movie seedha dikhta hai ???? I am sorry of you cant understand my doubt maine try kiya acche se samjhane ka please anyone clear my doubt 🧐 please

To find that sunlight is mixture of seven colours we can use Newton's disc it contains seven colours of rainbow and when we rotate it very fast then we can clearly see the white colour and then we can say that sunlight is mixture of seven colours of rainbow

A biconvex lens is the type of lens found in the human eye, and it is responsible for forming genuine images. It works by focusing light rays onto the retina. The eye lens is made up of peculiar elongated cells that have no blood supply and rely on the aqueous humor for nutrition.
