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.

True, because energy, frequency, and wavelength are all properties of sound, and sound is an electromagnetic wave. The electromagnetic spectrum encompasses a continuous range of frequencies or wavelengths of electromagnetic radiation, ranging from long wavelength, low energy radio waves to short wavelength, high frequency, high energy gamma rays.

10% of 3,000 is 300. (10% = 10/100 = 1/10, 3,000 ÷ 10 = 300)
3,000 minus 300 is 2,700.
