Question

assertion and the reason


A light ray makes an angle of incidence 60º, when it falles on a plane reflecting sheet Through the given cross-section of the conductor 10,800e  are passing within one hour. 89. The total charge transferred is (a) 19 17280 10 C   (b) 19 12780 10 C   (c) 19 18270 10 C   (d) 19 10800 10 C

i want only right answer so i can mark you brainliest

Answer 1

Answer:

Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees (90 - 30 degrees) with the mirror surface.
