Jessie creates a model of two waves that have the same amplitude as shown.
which description best compares the two waves?

wave b has less energy because it has a lower frequency and a longer wavelength.

wave a has less energy because it has a higher frequency and a shorter wavelength.

wave b has greater energy because it has a higher frequency and a shorter wavelength.

wave a has greater energy because it has a lower frequency and a longer wavelength.

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?
