Calculate the frequency of the red light emitted by a neon sign with a wavelength of 690 nm

Ne4ueva [31]

Answer:

$4.35 \times 10^{14} Hz$

Explanation:

The frequency of a light is inversely proportional to its wavelength. It is given by:

$f = \frac{v}{\lambda}$

The speed of the red light, v = 3.0 × 10⁸ m/s

The wavelength of the red light, λ = 690 nm = 690 ×10⁻⁹ m

$f = \frac{3.0 \times 10^8 m/s}{690\times 10^{-9}m} = 4.35 \times 10^{14} Hz$

Thus, the frequency of red light emitted by neon sign having wavelength 690 nm is $4.35 \times 10^{14} Hz$
