Physics P5

?
What is the equation to work out the refarctive index of a material?
Light speed in vacuum / Light speed in substance. Or sin i / sin r.
1 of 8
Simply expain what total internal reflection is
When the incident ray is at an angle greater than the critical angle. Occurs in a dense material.
2 of 8
What type of reflection does an endoscope use?
Total Internal Reflection.
3 of 8
What size does a wave have to be to cause maximum diffraction?
The wave has to be of the same size as the hole that it is passing through.
4 of 8
What is the most common cause of interferance?
Two radiowaves of the same frequency passing over eachother.
5 of 8
What is the difference between scalar and vector?
Scalar = Size Vector = Size and direcction
6 of 8
What is the difference between velocity and speed?
Velocity has speed and direction and speed. Speed is only a measurement.

Name one of the equations for motion...
V = U+AT V(squared) = U(sqaured) + 2AS S = UT + 1/2AT(squared)
