Waves
What is a disturbance through different media?
a wave
What are the two properties of waves?
Frequency and Wavelength
What is the only wave on the EMS we can see?
Visible light
What is the bouncing back of a light wave after it hits a surface?
reflection
Radiation, conduction and convection
What is the physical environment that waves occur in? (Hint: Types of matter: solid, liquid, gas)
medium
True or False. All electromagnetic waves travel at the same speed in a vacuum.
True
Which light wave shares the same name as the sound we hear in cars?
Radio waves
What is the bending of a light wave as it passes from one medium into a different medium?
refraction
What are the 3 light behaviors?
Reflection, Refraction and Absorption
What are waves the require a medium (such as sound)?
Mechanical waves
What is the distance from a point on one wave to the same point on the next wave?
wavelength
What are the 3 waves given off of the sun?
Visible, Infrared and UV
What electromagnetic waves have the highest frequency?
gamma rays
True or False. Heating up liquids increases its density.
What are waves that do not require a medium? (Such as light)
electromagnetic waves
How do sound waves travel in the different media?
Solids=fast
Liquids=medium
Gases=slow
Which has the longest wavelength, red or violet?
What is red?
What is the definition of an echo?
An echo is a sound wave reflecting off the surface of an object.
Which color absorbs all light?
What is black?
What is the fastest wave?

List all the colors on the visible light spectrum.
What is ROYGBIV (Red, orange, yellow, green, blue, indigo and violet)
White light takes in most colors and reflects the color we see. What light behavior is this?
What is absorption?
