Question
Use the image of the electromagnetic spectrum to answer the question.
The illustration describes the different wavelengths in decreasing order and the frequency in increasing order from left to right. The radiations shown are as follows: the radio waves (AM, FM, TV, and radar), wavelength from 100 m to 1 cm. Infrared (TV remote), wavelength from 1 cm to 1000 nm. Visible spectrum (light bulb) wavelength from 1000 nm to 10 nm. X-rays (X-ray machine) wavelength from 10 nm to 0.01 nm. Gamma rays (radioactive elements) wavelength from 0.01 nm to 0.0001 nm.
Lightning contains gamma rays. Based on the position of gamma rays in the electromagnetic spectrum, does lightning have more or less energy than a radio?

Lightning has more energy than the radio because gamma rays have a shorter wavelength.
Based on the position of gamma rays in the electromagnetic spectrum, lightning has more energy than a radio. This is because gamma rays have a shorter wavelength.
To determine whether lightning has more or less energy than a radio based on their positions in the electromagnetic spectrum, we need to understand the relationship between wavelength and energy. In general, electromagnetic waves with shorter wavelengths have higher energy.
Looking at the electromagnetic spectrum, we can see that gamma rays have the shortest wavelength, followed by X-rays, visible light, infrared, and radio waves. Therefore, gamma rays have higher energy than radio waves.
Since lightning contains gamma rays, which are higher up on the electromagnetic spectrum than radio waves, we can conclude that lightning has more energy than a radio.
Therefore, the correct answer is:
Lightning has more energy than the radio because gamma rays have a shorter wavelength.
