Question

a) state the 2 laws of reflection
b) in the figure given below label the following-
(i)angle i (write the value)
(ii)reflected ray
​

Answer 1

laws:

• angle of incidence is equal to angle of reflection
• incident ray, reflected ray and normal lie on same plane..
• angle i =90-70 (normal is perpendicular to reflecting surface)
• angle i =20°
• angle r =angle i=20°(first law)

hope it helps u
