Parts/types of Waves
What is the high point of a transverse wave?
Crest
What is an electromagnetic wave?
A type of wave that can travel through a medium or a vacuum
What wave behavior is it when a wave is bounced off of a surface?
Reflection
What is a mirror?
A smooth surface that reflects light to form images
What do waves move?
Energy
When particles in a longitudinal wave are far apart
Rarefaction
What type of wave is the electromagnetic spectrum?
Transverse
This is the bending of a wave as it enters a new medium
What is it called when a mirror is curved inwards?
Concave mirror
This is when some light passes through
Translucent
Give 2 examples of a mechanical wave
water waves, earthquakes, sound waves, springs, rope, slinkies
What wave (not color) is next to red?
Infrared
If a wave hits a mirror at 60 degrees, what will it be reflected at?
60
The focal point is where light rays converge or diverge. What does it mean to converge?
The height of the transverse wave from the rest line to the crest or to the trough
What is a vacuum? Give 1 example of a vacuum
A vacuum is no matter! Space is an example
What does an electromagnetic wave move the fastest in?
A vacuum
What causes a greater diffraction?
A larger wavelength compared to the size of the obstacle
Give an example of a virtual image
Reflections in mirrors or an image in a magnifying glass
What does light travel fastest in?
What type of wave is it?
Vacuum
Electromagnetic
Which type of wave only moves in 1 type of way? AND what way does it move?
Electromagnetic
Transverse
What is the mnemonic (saying) that helps us remember the order of the electromagnetic spectrum?
Raging Martians Invade Venus Using X-ray Guns
We see colors that are reflected. What happens to all of the other visible wavelengths?
They are absorbed
What kind of image is produced from the lens in a projector? How do we know?
A real image - because the image is projected into the REAL world
A student is wearing glasses with pink colored lenses. There are 2 wave behaviors here, what are they?
Pink is being reflected, all other light is being transmitted
