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 classified by wavelength. All electromagnetic waves travel at the speed of light in a vacuum, so velocity doesn't distinguish types. EM - radiation is neutral, so no charge to measure, and it has no rest - mass. Measuring wavelength allows identification as different types of EM - radiation (like radio, infrared, visible light, etc.) have distinct wavelength ranges.

Answer:

Measure the wavelength
