The speed of light in a diamond is 1.22 x 108 m/s. Calculate the index of refraction for a diamond.

The index of refraction of a diamond is 2.4175

Explanation:

refractive index

n = c/v

n = refractive index

c = speed of light

v = velocity of light thru the material

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
