200
the number of vibrations per second

200
This is how high or low a sound is
What is pitch?
200
radio waves, microwaves, infrared waves, x-rays, and visible light

What is a convex lens?
200
glass, water bottles, plastic wrap
What is transparent?
300
the bending of light rays
What is refraction?
300
This is how sound travels
What are compression waves?
300
This is how light travels
What are transverse waves?
300
Light makes spread out
What is a concave lens?
300
the bouncing of light from a surface
What is reflection?
400
A lens that is thinner in the middle and makes an object appear smaller.
What is a concave lens?
400
Sound waves cannot travel without this
What is a medium?
400
The bending of light as it moves from one material to another
What is refraction?
400
What makes a red object appear to be red?
The object absorbs the other colors and reflects red light waves.
400
How are sound and light similar?
They both travel in waves and are forms of energy
500
the back-and-forth movement of matter
What is vibration?
500
Does a bass or a violin play at a higher pitch? Why?
Violins have shorter strings, which causes the strings to vibrate faster. The faster the vibrations, the higher the frequency. A sound with a high frequency has a high pitch.
500
Why can you see your image in a calm lake but not when you look at the ground?
A calm lake has a smooth surface and the ground does not.
500
What causes light to separate in colors?
When there is rain, sunlight passes through drops of water in the air. The light waves refract as they enter and leave each drop. Each color bends in a slightly different way.

How are sound and light different?
Light can travel in empty space. Sound has to have a medium.
