GWHS: Photon Energy_2024

Front

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

Back

λ = hc/E, where λ is wavelength, h is Planck's constant, c is the speed of light, and E is energy.

Front

What happens to the energy of light as its frequency increases?

Back

The energy of light increases as its frequency increases.

Front

How do you calculate the energy of a photon given its frequency?

Back

E = hf, where E is energy, h is Planck's constant, and f is frequency.

Front

What is the energy of a photon with a frequency of 5x10^14 Hz?

Back

3.3x10^-19 J.

Front

What is the relationship between wavelength and energy of a photon?

Back

Shorter wavelengths correspond to higher energy photons.

Front

What is Planck's constant?

Back

Planck's constant (h) is approximately 6.626 x 10^-34 J·s.

Front

What is the speed of light in a vacuum?

Back

The speed of light (c) is approximately 3.00 x 10^8 m/s.

Front

What is the behavior of light as both a particle and a wave called?

Back

Wave-particle duality.

Front

What is the highest energy wavelength among visible light?

Back

Violet light has the highest energy among visible wavelengths.

Front
