Mini-Quiz: Laser Battle Game

by Ron Kurtus (revised 14 February 2016)

Take this Mini-Quiz to check your understanding of the lesson material.



1. How can a laser be used to destroy the missiles?

It is so bright that it burns a hole in the missile

It explodes on impact

It is faster than a speeding bullet

2. If this battle was in space, why shouldn't the enemy missiles make noise when they explode?

Laser explosions don't cause much noise

They did make noise we could hear

There is no air in outer space

3. Should the spaceship recoil when firing the laser?

Only rifles have a recoil

Slightly because of the momentum of the beam

Not according to the conservation of momentum

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
