Waves Test

Front

What is interference in the context of waves?

Back

Interference is the phenomenon that occurs when two or more waves overlap and combine, resulting in a new wave pattern.

Front

What portion of the electromagnetic spectrum does visible light occupy?

Back

Visible light lies in the middle of the electromagnetic spectrum and makes up only a small portion of it.

Front

What happens to visible light when it travels through different media?

Back

As visible light travels through different media, it undergoes a change in speed that may result in refraction.

Front

Which type of rays can cause sunburn?

Back

Ultraviolet rays can cause sunburn.

Front

What type of waves does a TV remote use?

Back

A TV remote uses infrared waves.

Front

Define refraction in the context of light waves.

Back

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

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and the spreading out of waves when they pass through small openings.

Front

What are gamma rays?

Back

Gamma rays are high-energy electromagnetic waves with very short wavelengths, often emitted by radioactive materials.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light waves when they hit a surface, while refraction is the bending of light as it passes through different media.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.
