For critical angle we will use snells lawC is critical angle and C 45onmedium sinC nair sin90 nair 1sinC S inC 1 sin451 nmedium 141we know that refractive index n speedof lightinmediumspeedof lightinvacuum where c 3108ms1414 vc v 14143108 v 212108ms. Then add the initial velocity to the increase in velocity. To calculate velocity using acceleration start by multiplying the acceleration by the change in time.
The speed of light is equal to the distance light travels d divided by the time it takes t.
The following formula is used to calculate the speed or velocity of a wave. Multiply the value by 062. V velocity of object in kms or ms depending on how the speed of light is measured c speed of light either 300000 kms or 30 x 10 8 ms change in wavelength from the normal can be measured in meters of A normal wavelength can be measured in meters or A. A handy trick if you dont have a calculator to hand eg youre driving is to use the Fibonacci sequence 1 1 2 3 5 8.
