What will most likely happen if a sound wave moves from the air through a solid?
It will increase in wavelength.
q It will decrease in speed.
It will increase in speed.
It will decrease in wavelength.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

The particles that are found in the nucleus of an atom are

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
