Which waves have the longest wavelength and the lowest energy on the electromagnetic spectrum?

1. X-rays
2. infrared
3. radio waves
4. gamma rays

3. radio waves

It's radio waves. I just found it in my book. It was hidden from my eyes. But thanks Anna and Elena! :) :D

Well, you're the one that found out the answer! but yes, the answer is "Radio waves" :)

radio waves is correct I checked on nasa's electromagnetic spectrum

The answers

radio waves

awesom i need the answers for it all

To determine which waves have the longest wavelength and the lowest energy on the electromagnetic spectrum, you can consider the following information:

The electromagnetic spectrum is a range of electromagnetic waves arranged in order of increasing frequency and decreasing wavelength. The spectrum includes various types of waves, such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Wavelength is the distance between successive crests or troughs of a wave, while energy refers to the ability of the wave to do work.

1. X-rays: X-rays have a relatively short wavelength and higher energy compared to other waves on the electromagnetic spectrum. Therefore, X-rays do not have the longest wavelength or the lowest energy on the spectrum.

2. Infrared: Infrared waves have longer wavelengths than visible light but shorter wavelengths than radio waves. They carry less energy compared to visible light but more energy compared to radio waves. Hence, infrared waves do not have the longest wavelength or the lowest energy on the spectrum.

3. Radio waves: Radio waves have the longest wavelength and the lowest energy among the options provided. They are used for various purposes, such as radio and television broadcasting, communication, and radar. Radio waves can have wavelengths from several centimeters to many kilometers.

4. Gamma rays: Gamma rays have the shortest wavelength and the highest energy among the options provided. They are produced through nuclear reactions and radioactive decay processes. Gamma rays are commonly used in medical treatments and for sterilization purposes.

Therefore, the correct answer is: 3. radio waves.

Gamma rays
