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?

Responses
Lightning has less energy than the radio because gamma rays have a longer wavelength.
Lightning has less energy than the radio because gamma rays have a shorter wavelength.
Lightning has less energy than the radio because gamma rays have a shorter wavelength.
Lightning has more energy than the radio because gamma rays have a longer wavelength.
Lightning has more energy than the radio because gamma rays have a longer wavelength.
Lightning has more energy than the radio because gamma rays have a shorter wavelength.
Lightning has more energy than the radio because gamma rays have a shorter wavelength.
Lightning has more energy than the radio because gamma rays have a shorter wavelength.
To determine whether lightning has more or less energy than a radio based on the position of gamma rays in the electromagnetic spectrum, we need to understand the relationship between wavelength and energy.
The electromagnetic spectrum is organized in order of increasing frequency (or decreasing wavelength) from left to right. As we move from left to right, the wavelength decreases and the frequency increases. Generally, the shorter the wavelength, the higher the energy of the radiation.
Gamma rays, which have the shortest wavelength in the electromagnetic spectrum, are associated with higher energy levels. On the other hand, radio waves, which have longer wavelengths, are associated with lower energy levels.
Since lightning contains gamma rays and gamma rays have a shorter wavelength (thus higher energy) than radio waves, we can conclude that lightning has more energy than a radio.
Therefore, the correct response is:
Lightning has more energy than the radio because gamma rays have a shorter wavelength.
