Electromagnetic Spectrum

Front

What happens to electrons in an atom when energy is absorbed?

Back

When atoms absorb energy, their electrons move to higher energy levels.

Front

What occurs when electrons return to lower energy levels after being excited?

Back

Electrons lose energy by emitting light.

Front

What type of lines are produced when electrons of an element reach an excited state?

Back

Emission (bright) lines are produced.

Front

Which wave in the electromagnetic spectrum has the greatest wavelength?

Back

The wave with the greatest wavelength is typically the one furthest to the right on the spectrum.

Front

How can each element on the periodic table be identified?

Back

Each element can be identified by its unique spectral 'fingerprint.'

Front

What is the formula to calculate the frequency of a photon given its wavelength?

Back

The frequency (v) can be calculated using the formula v = c/λ, where c is the speed of light and λ is the wavelength.

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 the relationship between wavelength and frequency in the electromagnetic spectrum?

Back

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

Front

What is a photon?

Back

A photon is a quantum of light or electromagnetic radiation.

Front

What is the significance of the electromagnetic spectrum?

Back

The electromagnetic spectrum encompasses all types of electromagnetic radiation, ranging from radio waves to gamma rays.
