What is newtons first law of motion

Gam radio signals can usually be heard behind a hill, but fm often cannot. that is, am signals bend more than fm. explain. (radio signals, as we shall see, are carried by electromagnetic waves whose wavelength for am is typically 200 to 600 m and for fm about 3 m.)

What happens to light waves from a star as the star moves away from earth?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?
