Which other type of electromagnetic wave will strip away electrons from the zinc plate? And why? A) Microwaves will strip electrons because we know these waves heat things up. B) Radio waves will strip away electrons because they are not a form of visible light. C) X-ray radiation will strip away electrons because it has a shorter wavelength and therefore more energy. D) Infrared radiation will strip away electrons because it is has a lower frequency and therefore more energy than visible light.

Answer:

C) X-ray radiation will strip away electrons because it has a shorter wavelength and therefore more energy

Step-by-step explanation:

The energy of an electromagnetic wave is inversely proportional to its wavelength, according to the equation:


E=(hc)/(\lambda)

where

h is the Planck constant

c is the speed of light


\lambda is the wavelength

In this problem, we are asked which electromagnetic wave is most likely to extract electrons from the zinc plate: the answer is 'the electromagnetic wave which carries more energy', which means the electromagnetic wave with shortest wavelength (given the equation above).

In order from shortest to longest wavelength, electromagnetic waves are:

Gamma rays

X rays

Ultraviolet

Visible light

Infrared

Microwaves

Radio waves

Among the choices provided, X-ray (choice C) are the electromagnetic waves with shortest wavelength, so they are the waves with highest energy, therefore choice C is the correct answer.
