Question

its time for the unit exam. this is your opportunity to show how much you have gained from all the work. if you dont feel ready, you may want to stop and clarify anything you do not understand. it may also be a good idea to go over any notes you have taken and review the key terms. good luck! note: to answer some of the questions, it may help to reference a periodic table. which statement correctly describes the properties of electromagnetic waves? the higher the frequency of the electromagnetic wave, the shorter the wavelength properties of electromagnetic waves are specific for each type and cannot be accurately described in a broad statement. the higher the frequency of the electromagnetic wave, the longer the wavelength the lower the frequency of the electromagnetic wave, the shorter the wavelength

Explanation:

Step1: Recall wave - frequency relationship

The relationship between the speed of light ($c$), frequency ($
u$), and wavelength ($\lambda$) of an electromagnetic wave is given by the formula $c =
u\lambda$. Since the speed of light in a vacuum is a constant ($c\approx3\times 10^{8}\ m/s$), when $
u$ increases, $\lambda$ must decrease to keep $c$ constant.

Step2: Analyze each option

• Option 1: The higher the frequency of the electromagnetic wave, the shorter the wavelength. This is consistent with the formula $c =

u\lambda$.

• Option 2: Electromagnetic waves have some general - properties that can be described by basic relationships like $c =

u\lambda$, so this option is incorrect.

• Option 3: It is the opposite of the correct relationship. Higher frequency should mean shorter wavelength, not longer.
• Option 4: Lower frequency should mean longer wavelength, not shorter.

Answer:

The higher the frequency of the electromagnetic wave, the shorter the wavelength.
