Question

Numerous devices utilize the electromagnetic spectrum, such as radios, cell phones, and medical equipment. When devising a device reliant on the electromagnetic spectrum, which category of waves would offer the highest energy to the device?

Responses:

waves that have shorter wavelengths and higher frequencies
waves that have shorter wavelengths and higher frequencies

waves that have shorter wavelengths and lower frequencies
waves that have shorter wavelengths and lower frequencies

waves that have longer wavelengths and lower frequencies
waves that have longer wavelengths and lower frequencies

waves that have longer wavelengths and higher frequencies

Answer 1

To determine which category of waves would offer the highest energy to a device reliant on the electromagnetic spectrum, we can refer to the relationship between wavelength, frequency, and energy.

The energy of electromagnetic waves is directly proportional to their frequency and inversely proportional to their wavelength. This means that waves with shorter wavelengths and higher frequencies carry more energy.

Based on this information, the correct response is:

waves that have shorter wavelengths and higher frequencies
