Question

Many devices use the electromagnetic spectrum including radios, cell phones, and medical equipment. When designing a device using the electromagnetic spectrum, which type of waves will provide the device with the most energy?

Group of answer choices

waves that have longer wavelengths and higher frequencies

waves that have longer wavelengths and lower frequencies

waves that have shorter wavelengths and lower frequencies

waves that have shorter wavelengths and higher frequencies

Answer 1

"Waves that have longer wavelengths and higher frequencies" type of waves will provide the device with the most energy.

Answer: Option A

Step-by-step explanation:

Red has maximum wavelength and minimum wavelength is in violet. The generation of white light take place, when all the waves are seen connected. In the phase of 10 nm to 400 the radiation which exist is Ultraviolet (UV) light, with a shorter wavelength than that of visible light but wider than X-rays.

The radio waves, microwaves, infrared, ultraviolet, X-rays and gamma-rays, from the maximum wavelength to the minimum is covered under electromagnetic spectrum. Here for communication purpose radio waves are used, consist maximum wavelength and more frequency than the rest. Such instruments obtain radio waves and transform them into mechanical vibrations to produce sound waves in the speaker.
