Asinger sings a note into a microphone. which of the parts of the wave would be affected by the microphone and how?
a) d, the frequency would get higher.
b) c, the wavelength would get longer.
c) c and d, the amplitude and wavelength would increase.
d) a, b and d. the amplitude and crest would be higher, while the trough would be lower.

D)A, B and D. The amplitude and crest would be higher, while the trough would be lower.

The microphone increases the amplitude. So the correct answer is A, B and D. The amplitude and crest would be higher, while the trough would be lower.

32: from largest to smallest, this hierarchy includes eons, eras, periods, epochs, and ages.

33: answer is c
