What is frequency in the context of waves?

Back

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

Front

What type of waves can cause sunburn?

Back

Ultraviolet (UV) waves are the type of waves from the sun that can cause sunburn.

Front

How does the energy of waves change with wavelength?

Back

The energy of waves increases as the wavelength gets shorter.

Front

What are microwaves used for?

Back

Microwaves are used to make water molecules vibrate and warm up, commonly used in microwave ovens.

Front

What are gamma rays?

Back

Gamma rays are high-energy waves emitted by radioactive materials and are part of the electromagnetic spectrum.

Front

What is amplitude in wave terminology?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What are radio waves used for?

Back

Radio waves are used for communication, including television, radio broadcasts, and cell phone signals.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation that is felt as heat and is used in remote controls and thermal imaging.
