What is the relationship between angle of incidence and angle of reflection? |
Angle of incidence is the angle of which the light hits an object. Angle of reflection is the angle that light is reflected back and is equal to the angle of incidence
Theta I=theta r |
|
|
What is index of refraction? |
Index of refraction = speed of light in a vacuum / speed of light through a medium
n=c/v
How much faster or slower light travels in a vacuum (faster) or through a medium (slower) |
|
|
What is the speed of light? |
C = 3.0 x 10^8 m/s |
|
|
What is the formula for C |
C = wavelength * frequency |
|
|

|
|
What is the formula for velocity |
Velocity =wavelength * frequency |
|
|
Energy of photon |
E = h x f
H= 6.63 x 10^-34 J*s |
