Electromagnetic Spectrum

Front

What are Gamma rays?

Back

Gamma rays are high-energy electromagnetic waves emitted by radioactive materials. They have the shortest wavelength and highest frequency in the electromagnetic spectrum.

Front

What is Ultraviolet (UV) radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation from the sun that can cause sunburn. It has a wavelength shorter than visible light but longer than X-rays.

Front

What are Radio waves used for?

Back

Radio waves are used to send signals for communication, including WiFi, radio broadcasts, and text messages. They have the longest wavelength in the electromagnetic spectrum.

Front

What is Wavelength?

Back

Wavelength is the distance from the peak of one wave to the peak of the next wave. It is a key characteristic of waves in the electromagnetic spectrum.

Front

How does increasing amplitude affect a wave?

Back

Increasing the amplitude of a wave increases the wave's energy. This means the wave can carry more energy.

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, categorized by wavelength and frequency.

Front

What are Microwaves?

Back

Microwaves are a type of electromagnetic radiation with wavelengths ranging from one meter to one millimeter. They are commonly used in microwave ovens and for communication.

Front

What is Frequency?

Back

Frequency is the number of waves that pass a point in one second. It is measured in Hertz (Hz) and is inversely related to wavelength.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is the speed of light?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s). It is the speed at which all electromagnetic waves travel.
