SMS Reflection and Refraction (2024-2025)

Front

Why do leaves appear to be green?

Back

Leaves appear green because they absorb all light wavelengths except green.

Front

What is the best diagram to show the absorption of light?

Back

A diagram illustrating the absorption spectrum of light, showing peaks for absorbed wavelengths and a dip for green.

Front

Why does a shirt appear white?

Back

A shirt appears white because it reflects all wavelengths of light.

Front

What type of mirror allows a shopkeeper to see a wider image of his store?

Back

A convex mirror allows a wider field of view.

Front

What is a lens that is thinner in the middle than on the outside called?

Back

A lens that is thinner in the middle than on the outside is called a concave lens.

Front

What is the principle of reflection?

Back

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

Front

What is refraction?

Back

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

Front

What is the difference between a convex lens and a concave lens?

Back

A convex lens is thicker in the middle and converges light rays, while a concave lens is thinner in the middle and diverges light rays.

Front

What happens to light when it passes through a prism?

Back

When light passes through a prism, it is refracted and dispersed into its component colors.

Front

What is the law of refraction, also known as 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 of incidence or refraction.
