Question

while performing an environmental survey, a physicist detects a high level of electromagnetic radiation in a controlled area. how can the physicist determine what kind of electromagnetic radiation is being detected?
measure the wavelength
measure the velocity
measure the charge
measure the mass

Explanation:

Electromagnetic radiation is characterized by its wavelength. Different types of electromagnetic radiation (such as radio - waves, microwaves, infrared, visible light, ultraviolet, X - rays, and gamma - rays) have distinct wavelength ranges. The velocity of electromagnetic radiation in a vacuum is a constant ($c = 3\times10^{8}m/s$). Electromagnetic waves are uncharged and massless.

Answer:

Measure the wavelength
