Good explanation! But i want to know how to calculate the angle of refraction/incidence to the calculator? can you explain?

[@Phantom_Deluxe7]

Here is another Noteworthy point, along with the same medium for refractive Index we should give an account for color too because colors have different Wavelengths since you may have seen when a light is passed through a prism the bottom color (last) is violet, and top in red, it is because violet (also blue) has lower wavelength and red (also orange) has more wavelength... Less wavelength=more bend towards normal and vice versa

hiii sir thank you for your explanation. I have a question, when I tried calculating the refractive angle (last problem in your video) I came out with the answer 30.71 degrees instead of your answer of 25.4 degrees, can you explain what i did wrong?

Sir it was very well explained but is the answer of the last qna is 33.33...

[@fatimafarrukh1763]

Wait really? Cause i am getting the same answer and i was thinking i was wrong

[@fatimafarrukh1763]

I applied the formula n = sin i/sin r. After doing sin(50) i inversed it then divided it by 1.5 to get 33.33

Sir how did u get the answers as r=25.4°. I got it as sin50° by sin1.5 as 33.3

[@Sucessbit]

Are bro jitna refractive index hoga utna speed kam rahega toh light bend hoga na aur jo velocity 1st medium me tha phir 2nd medium denser rahega toh speed kam hoga isliye voh bend hoga yeh hai refractive index vo measure karta hai jo light ka speed 1st medium pe aaye phir 2nd medium pe kitna speed kam hua
