Dual Nature of Light

Front

What is the relationship between wavelength and frequency?

Back

Inverse relationship: as wavelength increases, frequency decreases.

Front

What is the speed of electromagnetic radiation in a vacuum?

Back

3.00 x 10^8 m/s.

Front

What is the full range of frequencies of electromagnetic radiation called?

Back

The electromagnetic spectrum.

Front

How do you calculate the frequency of light given its wavelength?

Back

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

Front

What determines the color of visible light?

Back

Wavelength (and frequency).

Front

What is the wavelength of light emitted by an argon ion laser?

Back

488 nm.

Front

What is the frequency of light with a wavelength of 488 nm?

Back

6.14 x 10^14 Hz.

Front

What type of wave is light?

Back

Electromagnetic wave.

Front

What is the relationship between energy and frequency of light?

Back

Direct relationship: higher frequency means higher energy.

Front

What is the formula for calculating the energy of a photon?

Back

Energy (E) = Planck's constant (h) x Frequency (f).
