In a few words, describe the difference between sound and light.
"Students will be able to differentiate between refraction, reflection, and absorption"
Sound is the vibration of molecules that we hear as sound. Light is a form of energy that travels in waves and is visible to us. We can use sound and light to study the world around us!
Exploring Sounds & Light
Sound: A wave of energy created by vibrating objects. It is measured in units called decibels. Light: A form of energy that is visible to the human eye. It is made up of a range of colors, including red, orange, yellow, green, blue, indigo, and violet. Reflection: The bouncing of light off of a surface. Reflection is the reason why we can see things.
The speed of sound is three times faster in water than in air. Light travels at a speed of 186,000 miles per second. The human eye can distinguish up to 10 million colors.
