Mini-Quiz: X-ray Characteristics

by Ron Kurtus (30 January 2008)

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



1. How fast do x-rays travel?

It is impossible to measure their speed, since they are invisible

At the speed of light

At the speed of electrons

2. If x-rays go right through things, how can you see our bones in an x-ray picture?

The doctors usually draw in the bones with special software

Bones absorb more of the x-rays than softer and less dense materials

Your bones are made of lead

3. Why are x-rays dangerous?

They ionize atoms, which can injure or kill cells in your body

X-rays are very bright and can harm your eyes

They fog photographic film from miles away

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.


Look toward being great
