The correct answer is: D. Ultra violet rays
Visible light has the highest frequency, followed by ultraviolet rays, X-rays, and gamma rays.
- Visible light is the type of light that we can see with our eyes. It has a wavelength of about 400 to 700 nanometers.
- Ultraviolet rays have a wavelength of about 10 to 400 nanometers. They are invisible to the human eye, but they can cause sunburn and skin cancer.
- X-rays have a wavelength of about 0.01 to 10 nanometers. They are used in medical imaging and can also cause cancer.
- Gamma rays have the shortest wavelength of all electromagnetic radiation, at about 0.001 nanometers. They are the most powerful form of electromagnetic radiation and can cause severe damage to living tissue.
The frequency of electromagnetic radiation is inversely proportional to its wavelength. This means that the shorter the wavelength, the higher the frequency.
