a. The sound wave has a longer wavelength and has the slower speed.

b. The light wave has a shorter wavelength and has the slower speed.

c. The light wave has a longer wavelength and has the slower speed.

d. The sound wave has a shorter wavelength and has the greater speed.

e. The light wave has a shorter wavelength and has the greater speed.

f. The sound wave has a longer wavelength and has the greater speed.

g. The light wave has a longer wavelength and has the faster speed.

  • g)… The light wave will have a velocity of c whereas the velocity of the sound wave will be much lower… Therefore looking at v = f lambda, f is the same, but v is greater so therefore lambda is also greater…

  • A. sound waves require a medium to have the skill to pass Waves of electro-magnetic radiation (which contains seen easy, radio waves, x-rays, and radiation purely to call some) are self propagating and don’t require a medium to shuttle with the aid of. that’s why easy from distant stars can shuttle to Earth interior the direction of the vacuum of area.
