The speed of light =3×108m/s The speed of sound =3.43×102m/s The speed of light is almost 106 times that of sound
If the speed of light in air is 3 ×108 m/s and speed of light in water is reduced by a factor of 1.3 when compared with that of the speed of light in air. Find out the speed of light in water?
After 22 seconds of lightning, a thundering sound was heard. Calculate the height of the clouds which caused this lightning. Given, Speed of light = 3 x 108 m/s and Speed of sound = 340 m/s.
