Theories/Terms
Define electromagnetic waves.
What is a transverse wave composed of an oscillating electric field and a magnetic field that oscillates perpendicular to the electric field?
If light is traveling through air and then suddenly hit a glass window, the speed of light does this.
What is slows down?
You see a quarter in the bottom of a swimming pool about 3 ft in front of you, why is the quarter not really in front of you?
What is the bending of light as the light leaves the pool water causing a false image?
What shape is a converging lens?
What is convex?
The highest wavelength in visible light is what color?
Red
What is light is viewed as two transverse waves, one made of an oscillating magnetic field and the other an oscillating electric field?
Light(electromagnetic) waves travel fastest through what?
What is empty space?
Light is traveling through water and suddenly breaks the surface and travels through air. Did the speed increase, decrease, or stay the same once it left the water?
What is increase?
If you want to concentrate light coming from a weak light source by focusing it all on a single point. Would you use a converging or diverging lens to do this?
What is a converging lens?
What are all the colors of visible light?
*Bonus 100 points if you name them IN ORDER from least amount of frequency to highest amount of frequency*
Red, orange, yellow, green, blue, indigo, violet/purple
Define the Law of Reflection.
What is the angle of reflection equals the angle of incidence?
Define Einstein's Theory of Special Relativity.
Which electromagnetic waves have the longest wavelengths?
What are radio waves?
The cells in the human eye that determines color are _________.
What are cone cells?
If cyan and magenta ink is mixed, what color ink will you get?
What is blue?
Define the particle theory of light.
What is a ray of light is viewed as a beam of individual particles called photons?
Light that vibrates in only one direction.
What is polarized light?
Light hits a mirror, making an angle of 15 degrees relative to a line drawn perpendicular to the mirror's surface. What angle does the reflected light make with the same line?
What is 15 degrees?
What is a converging lens causes light rays to bend so that they converge to a single point, and a diverging lens causes light rays to bend away from each other?
If you shine red light on a yellow shirt, what color will the shirt appear (assume the shirt color is made with dyes using subtractive primary colors)?
What is red?
Define the quantum-mechanical theory.
What is light is both a particle and a wave and is made up of individual packets that behave like particles, but the packet is actually made up of a wave?
Materials in which light passes through but is scattered so that objects viewed through them become fuzzy are called _____________.
What is translucent?
Do radio waves have higher or lower frequencies than visible light?
What is lower?
What is special about the way the eye focuses light as compared to the way a camera focuses light?
What is the eye focuses light by changing the shape of its lens and a camera focuses light by moving the position of the lens?
If a computer monitor makes a green dot and then puts a blue dot in the same place, what color will you see?
What is cyan?
