What are Microwaves?

Back

Microwaves are a type of electromagnetic wave that can make water molecules vibrate, which is why they are used in microwave ovens to heat food.

Front

What is Frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is Amplitude?

Back

Amplitude is the height of a wave from its resting point, indicating the energy of the wave.

Front

How does wavelength affect energy?

Back

The energy of waves increases as the wavelength gets shorter.

Front

What are Gamma rays?

Back

Gamma rays are high-energy electromagnetic waves emitted by radioactive materials.

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.

Front

What is Wavelength?

Back

Wavelength is the distance between two consecutive peaks of a wave.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What are Radio waves?

Back

Radio waves are the longest wavelength electromagnetic waves, used for communication like radio and television.

Front

What are Ultraviolet rays?

Back

Ultraviolet rays are electromagnetic waves with shorter wavelengths than visible light, known for causing sunburn.
