Question

When a ray of light passes from one medium to another medium, refraction takes place when angle of incidence is a) 0° b) 45° c) 90°

Answer 1

your answer for this question is c)90°

Answer 2

Dear Student,

◆ Answer - (b)

When a ray of light passes from one medium to another medium, refraction takes place when angle of incidence is 45°.

● Explanation -

• When light is passed obliquely at interface from one medium to another medium, it gets deviated. This phenomenon is called refraction.
• For 0° (parallel) and 90° (perpendicular), angle of incidence in not oblique. They doesn't undergo refractions.
• For 45° angle of incidence, incident ray passes obliquely at interface. Hence, refraction takes place.

Thanks dear. Hope this helps you...
