which waves have the longest wavlength and lowest energy on the electromagnetic spectrum?

A. x-rays
B. infrared
C. radio waves
D. gamma rays

plz help i have three days to complete this lesson.

Do you have an ESRT?

It should tell you in there

I don't know what ESRT indicates, but you could Google "electromagnetic spectrum wavelengths" and start from there.

To determine which waves have the longest wavelength and lowest energy on the electromagnetic spectrum, you need to understand the relationship between wavelength and energy in the spectrum.

The electromagnetic spectrum consists of different types of waves, arranged in order of increasing wavelength and decreasing energy. Here, the longer the wavelength, the lower the energy of the wave.

So, to find the waves with the longest wavelength and lowest energy, you need to identify the end of the spectrum where the wavelengths are the longest.

Looking at the options provided:
A. X-rays have shorter wavelengths and higher energy. They do not have the longest wavelength.
B. Infrared waves have longer wavelengths than X-rays but shorter wavelengths than radio waves. They have higher energy than radio waves.
C. Radio waves have the longest wavelengths on the electromagnetic spectrum, stretching from a few millimeters (mm) to hundreds of meters. They also have the lowest energy among the options.
D. Gamma rays have the shortest wavelengths and the highest energy on the spectrum.

Based on this information, the correct answer is C. Radio waves have the longest wavelength and lowest energy on the electromagnetic spectrum.

Remember, when studying the electromagnetic spectrum, it is helpful to visualize the different types of waves arranged in order from left to right, starting with radio waves, then microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and finally, gamma rays.
