Question 1

Which region of the electromagnetic spectrum has the shortest wavelength according to the diagram provided?

Accepted Answer

Gamma rays

Question 2

Based on the electromagnetic spectrum diagram, which type of radiation has a wavelength just shorter than visible light?

Accepted Answer

Ultraviolet

Question 3

If a photon has a wavelength of $1 	imes 10^{-10}$ m, which region of the electromagnetic spectrum does it belong to?

Accepted Answer

X-rays

Question 4

Which of the following correctly lists the regions of the electromagnetic spectrum in order of increasing frequency?

Accepted Answer

Radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, gamma rays

Question 5

A student claims that microwaves have a higher energy per photon than ultraviolet light. Based on the electromagnetic spectrum, is this claim correct?

Accepted Answer

No, because ultraviolet light has a higher frequency and thus higher energy per photon.

Question 6

Which of the following best explains why gamma rays are more dangerous to living tissue than visible light?

Accepted Answer

Gamma rays have much higher energy per photon due to their shorter wavelength.

Question 7

According to the electromagnetic spectrum, which type of radiation is used in medical imaging to view bones?

Accepted Answer

X-rays

Question 8

If the wavelength of a photon is $5 	imes 10^{-7}$ m, which region of the electromagnetic spectrum does it fall into?

Accepted Answer

Visible light

Question 9

Which of the following statements is true about the speed of electromagnetic waves in a vacuum?

Accepted Answer

All electromagnetic waves travel at the same speed in a vacuum.

Question 10

A remote control uses electromagnetic radiation with a wavelength of about $1 	imes 10^{-5}$ m. Which region of the spectrum does this correspond to?

Accepted Answer

Infrared

Question 11

Which region of the electromagnetic spectrum is most commonly associated with sunburn?

Accepted Answer

Ultraviolet

Question 12

If the frequency of a photon is doubled, what happens to its wavelength?

Accepted Answer

The wavelength is halved.
