Question

fill in the blanks underneath the wave spectrum to indicate the relative positions of each type of electromagnetic radiation from the given word bank.
circle the correct answer
a) which has a longer wavelength? microwaves or infrared
b) which has a lower frequency? x - rays or gamma rays
c) which has a higher frequency? visible or ultraviolet
d) which has more energy? radio/tv or infrared
e) which has more energy? red light or green light
f) which has a higher frequency? orange light or blue light
g) which has a shorter wavelength? ultraviolet or x - rays

Explanation:

Step1: Recall electromagnetic - spectrum properties

In the electromagnetic spectrum, wavelength and frequency are inversely related ($c = \lambda
u$, where $c$ is the speed of light, $\lambda$ is wavelength, and $
u$ is frequency), and energy is directly related to frequency ($E = h
u$, where $h$ is Planck's constant).

Step2: Compare wavelengths and frequencies

• Microwaves have longer wavelengths than infrared.
• X - rays have a higher frequency than gamma rays.
• Ultraviolet has a higher frequency than visible light.
• Infrared has more energy than radio/TV waves.
• Green light has more energy than red light (higher frequency).
• Blue light has a higher frequency than orange light.
• X - rays have shorter wavelengths than ultraviolet.

Answer:

A. Microwaves
B. X - rays
C. Ultraviolet
D. Infrared
E. Green light
F. Blue light
G. X - rays
