Awave with a high frequency generally has a
a. low amplitude
b. high amplitude
c. long wavelength
d. short wavelength

D. short wavelength

Explanation:

The frequency of a wave is inversely proportional to its wavelength. In fact, the relationship between the two quantities is the following:

where

is the wavelength

v is the wave speed

f is the frequency

From the equation, we see that:

- the higher the frequency, the shorter the wavelength

- the lower the frequency, the longer the wavelength

So, a wave with a high frequency generally has a short wavelength.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
