LIGHT AND SOUND Hardback

Description

Our world is largely defined by what we see and hear-but our uses for light and sound go far beyond simply seeing a photo or hearing a song.

A concentrated beam of light, lasers are powerful tools used in industry, research, and medicine, as well as in everyday electronics like DVD and CD players.

Ultrasound, sound emitted at a high frequency, helps create images of a developing baby, cleans teeth, and much more.

Light and Sound teaches how light and sound work, how they are used in our day-to-day lives, and how they can be used to learn about the universe at large.
