Question

Найдите частоту колебаний,соответствующую крайнему фиолетовому лучу спектра (^=0,4мкм)

Answer 1

L - длина волны. 
c - скорость света
V - частота

L=с/V  => V=c/L
V = 3*10^8 (метров в секунду) / 0,4*10^(-6) (метра) = 7,5*10^14 Герца.

Answer 2

Finding the Frequency of the Extreme Violet Ray

The frequency of the extreme violet ray can be calculated using the formula:

f = c / λ

Where: - f = frequency - c = speed of light in a vacuum (approximately 3.00 x 10^8 m/s) - λ = wavelength of the extreme violet ray (given as 0.4 μm)

Calculation

Substitute the given values into the formula:

f = (3.00 x 10^8 m/s) / (0.4 x 10^-6 m)

f ≈ 7.50 x 10^14 Hz

Therefore, the frequency corresponding to the extreme violet ray with a wavelength of 0.4 μm is approximately 7.50 x 10^14 Hz.
