Question
2.Electromagnetic waves are traveling straight down towards the center of the earth. For these waves...
A) visible light has a shorter wavelength than infrared light
B) if the electric field points north, the associated magnetic field points east
C) a high-frequency wave has a longer wavelength than a low-frequency wave
D) if the electric field points east, the associated magnetic field points north
E) green light has a higher frequency than violet light
3. [3pt] Electromagnetic waves are traveling straight down towards the center of the earth. For these waves...
A) Ultraviolet light has longer wavelength than infrared.
B) X-rays have longer wavelength than infrared waves.
C) Blue light has higher frequency than X-rays.
D) Green light has higher frequency than infrared waves.
E) Radio waves have higher frequency than ultraviolet rays.
Explanation / Answer
2)
A) visible light has a shorter wavelength than infrared light
because visible light has the wavelength range from 400 nm to 700 nm, while infrared have wavelengths ranging from 700 nm to 1 mm
3)
D) Greenlight has a higher frequency than infrared waves.
Greenlight frequency is from 540 - 580 THz
Infrared frequency is from 300 GHz to 430 THz
