Question

If a wave of red light has a wavelength of 6.7 x 10-7 m, what is the frequency of the red wave?

Answer 1

The frequency of the red wave, f = 2.78 x10¹¹ Hz.

Equation :

To find the wavelength,

f = v / λ

where,

f is frequency

v is speed wave of light

λ is wavelength of light

Known data,

wavelength of light, λ = 6.7 x 10⁻⁷

speed of red light, v = 1.86 x 10⁵

f = ?

f = 1.86 x 10⁵ / 6.7 x 10⁻⁷

f = 2.78 x 10¹¹Hz

Frequency :

The number of waves that pass a fixed place in a unit of time is referred to as frequency. It also indicates how many cycles or vibrations a body in periodic motion experiences in a given unit of time. The formula for frequency expressed in terms of time is given as follows: f = 1/T, where f is the frequency expressed in hertz and T is the duration of one cycle expressed in seconds.
