Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

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

Front

What is the formula to calculate wavelength (λ) from frequency (v)?

Back

λ = c/v, where c is the speed of light (approximately 3.00 x 10^8 m/s).

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second.

Front

What is frequency?

Back

Frequency is the number of occurrences of a repeating event per unit of time, typically measured in Hertz (Hz).

Front

What is wavelength?

Back

Wavelength is the distance between successive peaks of a wave, usually measured in meters.

Front

What type of spectrum shows dark lines on a continuous spectrum?

Back

Absorption spectrum.

Front

What happens when an electron absorbs energy?

Back

When an electron absorbs energy, it moves from a lower energy level to a higher energy level.

Front

What is an emission spectrum?

Back

An emission spectrum is produced when electrons fall from higher energy levels to lower energy levels, emitting light at specific wavelengths.

Front

What color of light corresponds to a wavelength of approximately 5.93 x 10^-7 m?

Back

Green.

Front

What is the relationship between wavelength and frequency?

Back

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