Answer:
500 THz .
Explanation:
Velocity of light in air = 3 x10⁸ m /s
wave length of light = 600 nm
= 600 x 10⁻⁹ m
= 6 x 10⁻⁷ m
frequency in air = velocity in air / wave length in air
= 3 x 10⁸ / 6 x 10⁻⁷
= .5 x 10¹⁵ Hz
= 5 x 10¹⁴Hz
= 500 x 10¹² Hz
= 500 THz
When light enters the medium of gem , its wavelength and velocity changes in such a way that its frequency remains constant. So in the medium of gem also its frequency remains 500 THz .
Answer:
they are constantly bouncing everywhere and creating preasure
