As the frequency of a wave increases... A.)the energy carried by the wave decreases
B.)the wavelength of the wave decreases
C.)the amplitude of the wave decreases
D.)the speed of the wave increases

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
