Paul stretches a slinky between his hands and begin experimenting with waves. As the frequency of the waves is doubled:

• a. the wavelength is halved and the speed remains constant

• b. the wavelength remains constant and the speed is doubled

• c. both the wavelength and the speed are halved.

• d. both the wavelength and the speed remain constant.
