Question

Which of the following statements is false?

A photon’s energy increases as its frequency increases.

As a photon’s wavelength increases, its frequency increases.

As the energy of a photon decreases, its wavelength increases.

The wavelength of a photon increases as its frequency decreases.

A photon with the longest wavelength has the lowest energy.

Answer 1

energy of photon = E = h*v = h*c/lemda where v=frequency and lemda is wavelength.

A photon’s energy increases as its frequency increases. TRUE because energy and frequency are directly proportional.

As a photon’s wavelength increases, its frequency increases. FALSE because wavelength and frequency are inversely related.

As the energy of a photon decreases, its wavelength increases. TRUE because wavelength and energy are inversely related.

The wavelength of a photon increases as its frequency decreases. TRUE because wavelength and frequency are inversely related.

A photon with the longest wavelength has the lowest energy. TRUE because wavelength and energy are inversely related.
