waves frequence wavelength velocity and speed of light

How is the motion of electromagnetic waves different from the motion of mechanical waves?

• The motion of mechanical waves can ONLY be transverse.

• The motion of mechanical waves can be transverse,

  longitudinal, or a combination of both.

• The motion of mechanical waves can ONLY be longitndinal.

What is the relationship between eyesight and light?

• Light shines on all objects, allowing people to see them.

• Light shines through all objects, allowing people to see them.

• Light enters the eye before striking an object, allowing people to see the object.

• Light reflects off an object and then enters the eye, allowing people to see the object.

How does changing the temperature of the medium (a solid, liquid, gas) affect the waves passing through it? Remember heat = energy

• It changes the speed of the waves.

• It changes the direction of the waves.

• It changes the amplitude of the waves.

• It changes the wavelength of the waves.
