Wavelengths, Frequency and Energy

Front

What is the relationship between frequency and wavelength in waves?

Back

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

Front

Define wavelength.

Back

Wavelength is the distance between successive crests (or troughs) of a wave.

Front

What happens to the energy of a wave as its frequency increases?

Back

The energy of a wave increases as its frequency increases.

Front

What is the formula to calculate the wavelength of a wave?

Back

Wavelength (λ) = Speed of Light (c) / Frequency (f).

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 m/s.

Front

How do you calculate the frequency of a wave if you know its wavelength?

Back

Frequency (f) = Speed of Light (c) / Wavelength (λ).

Front

What is the unit of frequency?

Back

The unit of frequency is Hertz (Hz).

Front

What type of wave has the highest energy?

Back

Gamma rays have the highest energy among electromagnetic waves.

Front

What is the ground state of an electron?

Back

The ground state is the lowest energy state of an electron in an atom.

Front

What occurs when an electron absorbs energy?

Back

When an electron absorbs energy, it moves from a lower energy state (ground state) to a higher energy state (excited state).
