What is the value for the speed of light in a vacuum?
What is 3 x 10^8 m/s
100
When the electric field of a light wave vibrates in only one dimention it is this.
What is polarized.
100
When two sources of water waves interact the dark and bright bands that result correspond to what?
What is interference patterns (constuctive/destructive)
100
If a wave encounters a barrier with a small opening so the wave can only move through that hole.
What is diffraction.
100
The region in the electromagnetic spectrum with the longest wavelength.
What Radio
200
The direction of motion for the electric field is perpendicular the direction of wave motion. What type of wave is this?
What is transverse.
200
Light from most sources tends to be this, meaning that the electric field vibrates in every direction equally.
What is unpolarized.
200
Bright rainbow-like patterns can be formed from the combination of these two types of interference patterns.
What is contructive and destructive.
200
Our argument for light being a wave is based on the behavior of light after passing through a small opening, if light behaved like a particle it would create a strait line of light. Because it behaves like a wave it does this:
What is spreads out.
200
The spectrum in the electromagnetic spectrum with the highest frequency.
What is gamma.
300
A changing magnetic field creates a changing electric field and vice versa is the explanation of what scientific theory.
What is Induction
300
Only light that is vibrating parrallel to this type of object will be passed through, perpendicular light is blocked.
What is polarizing filters.
300
Leading edge of a traveling wave.
What is a wave front.
300
When light goes through two or more slits the resulting interference patterns are separated into the central bright spot and higher order..these?
What are fringes.
300
The theorhetical physisist who postulated the existence of electromagnetic waves.
What is James Clerk Maxwell
400
The energy of the electromagnetic wave region is directly proportional to what characteristic of the wave?
What is frequency
400
If light is passed through a single filter 50% of the light will be blocked. If this light is passed through a second filter the amount of light that goes through is E = Eocosθ. (Important) The second filter is called this because the angle can be used to analyze the orientation of the first filter. (Not)
What is analyzing filter.
400
There are two ways to increase the energy of a light wave. One is increase the amplitude/amount of light, the other is:
What is increase the frequency/blueshift the light.
400
If white light is shined through a diffraction grating the light that creates the fringes separates into a spectrum based on this:
What is wavelength/color
400
The experimental physisist who successfully created and detected electromagnetic waves for the first time.
What is Heinrich Hertz
500
The type of circuit that can be used to create radio waves has two elements:
What is coil (L) and capacitor (C)
500
Glare that results when light is induced to vibrate in only one direction when reflected from a dialectric surface such as water. The angle that creates this is called: (This is not important for the test)
What is Brewster's angle.
500
The scientist who developed the concept of wave motion of light had this principle named after him. (Not important for the test - just bragging rights)
Who is Huygens
500
In the equation dsinθ = mλ there is no measurement for the values of: distance to the screen distance from central bright spot to fringe why?
What is the angle θ = arctan (x/L). For any angle θ the ratio of x/L remains a constant value.
500
One way to detect NATURAL gamma rays.
What is balloon measurements above the atmosphere.
