Ans:
b)State Rule 1 based on the laws of reflection of light.
Ans:
c)Define the radius of curvature.
Ans:
a)Find out the number of images that you obtained from 90° an
Ans:​

Answer 1

Answer:

ans1 - It's an equation related objects distance and image distance with focal length is known as mirror formula . ans 2- The law of reflection states that the incident ray and the normal to the surface of the mirror all lie in the same plane the angle of reflection is equal to the angle of incident. Ans3- the radius of a circle which touches a curve at the given point and has the same tangent and curvature at that point.Ans4-if two mirrors are inclined at an angle and this value of x is submultiple of 180 degree then the number of images formed is (360 divided by X)-1 ,here x is equal to 90 degree so number of images will be (360/90)-1=4-1=3
