Question

use the information and model to answer the following question. students are investigating how amplitude and frequency of electromagnetic waves respond as the waves travel through a vacuum. identify which of the following questions would best represent the students investigation. which electromagnetic wave will have the shortest amplitude when traveling in a vacuum? how does frequency affect the speed of an electromagnetic wave traveling in a vacuum? how does amplitude affect the speed of an electromagnetic wave traveling in a vacuum? which electromagnetic wave will have the shortest wavelength when traveling in a vacuum?

Explanation:

The students are investigating the relationship between amplitude, frequency and electromagnetic waves traveling in a vacuum. The given models show infrared and ultraviolet light traveling in a vacuum with the same speed, and focus on the wave - like nature in terms of amplitude and frequency. The question about how frequency affects the speed of an electromagnetic wave in a vacuum is not relevant as the speed of light in a vacuum is constant ($c = 300000$ km/s) and not affected by frequency. The question about how amplitude affects the speed is also incorrect for the same reason. The question about the shortest amplitude is too specific and not in line with the general investigation. The question about which electromagnetic wave has the shortest wavelength is related to the frequency - wavelength relationship ($c=\lambda f$) and is consistent with the investigation of how frequency and amplitude of electromagnetic waves behave in a vacuum.

Answer:

Which electromagnetic wave will have the shortest wavelength when traveling in a vacuum?
