Plz true or false. the electromagnetic spectrum can be described in terms of wave energy, frequency, and wavelength.
question 3 options:
a. true because energy, frequency, and wavelength are all properties of sound, and sound is an electromagnetic wave.
b. false because the electromagnetic spectrum is about radiation, not waves.
c. true because the electromagnetic spectrum is ordered based on wave energy, which is described on a wave as wavelength and frequency.
d. false because energy, wavelength, and frequency are only characteristics of mechanical waves.

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
