true or false. the electromagnetic spectrum can be described in terms of wave energy, frequency, and wavelength.
question 3 options:
true because energy, frequency, and wavelength are all properties of sound, and sound is an electromagnetic wave.
false because the electromagnetic spectrum is about radiation, not waves.
true because the electromagnetic spectrum is ordered based on wave energy, which is described on a wave as wavelength and frequency.
false because energy, wavelength, and frequency are only characteristics of mechanical waves.
an x-ray technician will place a lead cloth over parts of your body when taking an x-ray to protect your cells from being damaged. why do x-rays have the potential to harm your body but radio waves do not?
question 6 options:
x-rays have a much shorter wavelength than radio waves, and therefore carry more energy that can be transferred to your body.
radio waves are shorter than x-rays and therefore weaker in strength..
x-rays have a taller wavelength than radio waves as shown in the diagram, so they are more harmful.
radio waves have longer wavelengths than x-rays and therefore carry more energy than x-rays.
