Which of the following best explains why ultraviolet rays can cause sunburn but visible light from a light bulb does not damage skin?
Ultraviolet rays come before the light rays in the electromagnetic spectrum, which means anything before visible light automatically causes cancer.
Ultraviolet rays have lower frequencies than visible light rays and thus have higher energy than light rays from a light bulb.
Ultraviolet rays have higher frequency than visible light rays and thus have more energy than light rays from a light bulb.
Ultraviolet rays have higher frequencies than visible light rays and thus have less energy than light rays from a light bulb.
On the electromagnetic spectrum, radio waves are found on the end of the spectrum considered to possess a low amount of energy. Which statement most accurately describes the wavelength/frequency relationship present in radio waves?

When comparing infrared waves to X-rays, what relationships would you expect to see in terms of wavelength, energy, frequency, and why?
Because of their inverse relationship, infrared waves will have longer wavelengths with lower frequencies than that of X-rays.
Wavelength and frequency are directly related, so infrared waves will have longer wavelengths with higher frequencies than that of X-rays.
Wavelength and frequency are inversely related, so infrared waves will have longer wavelengths with higher frequencies than that of X-rays. Their energies will be the same.
Wavelength and frequency are directly related, so infrared waves will have longer wavelengths with lower frequencies than that of X-rays. Their energies will be the same.
The visible light that we can see travels in waves. Blue light has a wavelength of 450 nm and orange light has a wavelength of 600 nm. Based on this information, what is true about the energies of blue and orange light?
Energy of blue light will be higher than that of orange light.
Energy of blue light will be lower than that of orange light.
Energy of blue light and orange light will be the same.
Wavelengths of light and energy of light are independent of each other.
