Refraction
A beam of light enters enters a block of glass at an angle of 20 degrees from the normal. At what angle will it come out from
What is 20 degrees from the normal
what is the 90 degree line we use to measure the angle of incidence
what is the normal
This is how energy moves when something like a wave goes up and down or back and forth.
What is vibration?
This is what sound travels through, like air, water, or solids.
What is a medium?
A beam of light enters a block of glass at an angle of 30 degrees. At what angle will it come out from.
What is 60 degrees from the normal
The angle of reflection is equal to the angle of incidence
what is true
This type of wave moves particles perpendicular to the wave direction, like waves on a string or water.
What is a transverse wave?
This property of sound tells us how high or low a sound is.
What is pitch?
True or false: A translucent block has a greater angle of refraction than a transparent block.
False
A beam of light hits a mirror at 30 degrees to the normal at what angle will it bounce back from.
what is 30 degrees to the mirror
This is the space between two high points (crests) in a wave.
What is wavelength?
This property of sound describes how loud or soft a sound is.
What is volume?
This happens to the speed of light when it enters a denser material, like glass or water.
What is it slows down?
A beam of light hits a mirror at an angle of 15 degrees at what angle will it bounce back from relative to the normal?
what is 75 degrees
This tells how many waves happen in one second.
What is frequency?
This is how fast sound waves travel through a medium.
What is the speed of sound?
This lense with a bulge in the center causes light to come together to a single point.
what is a convex lense
True or false:
An angle of 45 degrees not relative to the normal is equal to an angle of 45 degrees relative to the normal.
what is true.
What is the name of the part of a wave where it is the highest?
what is the crest
This happens when sound waves bounce off a surface and return to you.
What is an echo?
