Question

is headlights a reflection or refraction?​

Answer 1

Answer:

When parallel beams of light strike a lens that is convex on both sides (double convex lens) the light is refracted inwards and is said to be converging (A). The beams of light cross at a point called the focal point which is behind the lens (to the right of the lens).

Answer 2

Answer:

Refraction

Explanation:

Refraction

• This phenomenon usually occurs in lenses.
• Refraction can be defined as the process of the shift of light when it passes through a medium leading to the bending of light.
• The light entering the medium travels from one medium to another.
• During refraction, the light waves pass through the surface while simultaneously changing both direction and medium.
• The angle of incidence is not equal to the angle of refraction.
• Example: Formation of a rainbow

Reflection

• This phenomenon usually occurs in mirrors.
• Reflection can simply be defined as the bouncing back of light when it strikes the medium on a plane.
• The light entering the medium returns to the same medium.
• Considering the light waves, they bounce from the plane and change direction.
• The angle of incidence of the light is equal to the angle of reflection.
• Example: Reflection by a plane mirror.
