Front

What color of visible light has the highest frequency?

Back

Violet has the highest frequency among visible light waves.

Front

What is wavelength?

Back

Wavelength is the distance between two crests or two troughs of a wave.

Front

What type of electromagnetic wave has a higher frequency than visible light?

Back

Ultraviolet waves have a higher frequency than visible light.

Front

What is the role of ultraviolet waves in medicine?

Back

Ultraviolet waves are used to sterilize medical equipment.

Front

Which electromagnetic waves are used for television transmission?

Back

Radio waves are used for television transmission.

Front

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

Back

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

Front

What type of electromagnetic radiation is used in microwave ovens?

Back

Microwaves are used in microwave ovens to heat food.

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 infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, commonly felt as heat.
