Question

How will you prove the first law of reflection of light with the help of ray box?

Answer 1

Answer:

According to the first law of reflection. θi = θr

Explanation:

• First law of reflection of light states that
• The incident ray, the reflected ray and the normal all lie in the same plane.
• Furthermore, it states that the angle of incidence is equal to the angle of reflection.
• i.e. θi = θr
• Where
• θi = angle of incidence
• θr = angle of reflection
• Therefore according to the first law of reflection.
• θi = θr
