Explore Light Behavior Through Reflection and Refraction

Front

What is reflection in terms of light behavior?

Back

Reflection is the bouncing back of light when it hits a surface.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

Front

What is the normal line in the context of light?

Back

The normal line is an imaginary line that is perpendicular to the surface at the point of incidence.

Front

What does the term 'refractive index' mean?

Back

The refractive index is a measure of how much light slows down in a substance compared to its speed in a vacuum.

Front

What happens to light when it enters a denser medium?

Back

When light enters a denser medium, it slows down and bends towards the normal line.

Front

What happens to light when it enters a less dense medium?

Back

When light enters a less dense medium, it speeds up and bends away from the normal line.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What is an example of a material that does not refract light?

Back

A mirror does not refract light; it reflects it.

Front

How does the angle of incidence relate to the angle of refraction?

Back

The angle of incidence and the angle of refraction are related by Snell's Law.

Front

What is Snell's Law?

Back

Snell's Law states that n1 * sin(θ1) = n2 * sin(θ2), where n is the refractive index and θ is the angle.
