I think Jamal should put the purple car so
where point A(s) faces in N and then B
faces the back. Or, he can move the green
car to where it should be part D(n) faces S
and part C faces the back. I think this

+ N facing each other, it won't move the
car at all and it would force each other

facing each other, it won't move the car at
all and it would force each other apart.

Describe the relationship between wavelength and the energy of the wave.

Answers

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
