Reflection, Refraction, Absorption

Front

What is reflection in terms of light waves?

Back

Reflection is the bouncing back of light waves when they hit a surface that does not absorb the light.

Front

What is refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another, changing speed.

Front

What is absorption in the context of light?

Back

Absorption is the process by which an object takes in light waves and converts them to energy, preventing them from being reflected or transmitted.

Front

What happens to light when it hits a black object?

Back

A black object absorbs all colors of light and reflects none, making it appear black.

Front

Which color of light has the highest energy?

Back

Violet light has the highest energy among visible colors.

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves carry more energy than lower frequency waves.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

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 the difference between a concave and a convex mirror?

Back

A concave mirror curves inward and can focus light, while a convex mirror curves outward and spreads light.

Front

How does the color of an object affect its temperature when exposed to light?

Back

Darker colors absorb more light and heat, making them warmer than lighter colors.
