Insta I'd :prithvi dj plz follow guys

Answer 1

Explanation:

Reflections of light -

• Light travel in a straight direction
• Bouncing back of light is called Refraction

Law of Refraction-

• The angle of incidence is equal to the angle of refraction i.e i = r
• The incident ray common ray and refracted ray lie on the same plane

plane mirror-

• The size of object equal to size of image
• Height of object is equal to Height of image
• The of is form behind the mirror.
• It always form Virtual and erect image
• The image is laterally inverted

Thanks...

Answer 2

following are the laws of reflection:-

*The incident ray ,the reflected ray and the normal to the surface of the mirror all lie in the same plane .

*The angle of incidence is equal to the angle of reflection.
