What is an emission spectrum?

Back

An emission spectrum is a spectrum of the electromagnetic radiation emitted by a source, showing specific lines of light corresponding to the energy levels of electrons in atoms.

What is the difference between ground state and excited state in an atom?

Back

The ground state is the lowest energy state of an atom, while the excited state is a higher energy state that occurs when an electron absorbs energy and jumps to a higher energy level.

Front

Which color of visible light has the highest energy?

Back

Violet has the highest energy among visible light colors.

Front

Which color of visible light has the lowest energy?

Back

Red has the lowest energy among visible light colors.

What type of waves are used for cell phone communication?

Back

Radio waves are used to send signals for cell phones, WiFi, and text messages.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

Front

What is frequency?

Back

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

Front

How are wavelength and frequency related?

Back

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

Front

What type of radiation has the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.
