The wavelength of a wave doubles as it travels
from medium a into medium b. compared to the
wave in medium a, the wave in medium b has
(1) half the speed
(2) twice the speed
(3) half the frequency
(4) twice the frequency

Acrow drops a 0.11kg clam onto a rocky beach from a height of 9.8m. what is the kinetic energy of the clam when it is 5.0m above the ground? what is its speed at that point?
