light and sound waves Unit 4 review

Front

A student views a table of the speed of sound waves in three different materials. Which conclusion can be drawn based on the information in the table?

Back

Sound travels faster in glass because it has a higher density than the other materials.

Front

Why do sound waves travel faster in salt water than in fresh water?

Back

Fresh water is less dense than salt water.

Front

Why does there appear to be another duck head in the water in the picture of a duck swimming in a pond?

Back

The water in the pond reflects light from the Sun, making a mirror image.

Front

The distance between the line of origin to the top of the wave is called

If the distance represented by the letter A were increased, how would it change the way the sound was heard?

Back

The sound would be louder.
