What does a mirror do to light?

Back

A mirror reflects light.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, often used to describe electromagnetic waves.

Front

Which type of electromagnetic wave has the longest wavelength?

Back

Radio Waves have the longest wavelength and the lowest frequency/energy.

Front

What type of electromagnetic waves are used in X-ray imaging?

Back

X-rays are used to help doctors detect broken bones inside the body.

Front

What is the relationship between frequency and energy in electromagnetic waves?

Back

Higher frequency electromagnetic waves have higher energy, while lower frequency waves have lower energy.

Front

What is the visible light spectrum?

Back

The visible light spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from about 400 nm (violet) to 700 nm (red).

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the highest frequency and energy, often used in cancer treatment.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What is amplitude in a wave?

Back

Amplitude is the height of the wave from its rest position to its crest, indicating the energy of the wave.
