Question

An emission ray has a frequency of 5.10 × 1014 Hz. Given that the speed of light is 2.998 × 108 m/s, what is the wavelength of the ray?

a. 5.878 × 10-7 m
b.15.2898 × 10-7 m
c.15.2898 × 107 m
d.0.5878 × 10-9 m

Answer 1

A. is ur answer, it consists with the wavelength, speed of light and frequency.

Answer 2

Answer:
`5.878* 10^(-7)m`

Explanation:

The relationship between wavelength and frequency of the wave follows the equation:

`\\u=(c)/(\lambda)`

where,

`\\u` = frequency of the wave =
`5.10* 10^(14)Hz`

c = speed of light =
`3* 10^8ms^(-1)`

`\lambda` = wavelength of the wave = ?

Putting in the values we get:

`5.10* 10^(14)=(3* 10^8)/(\lambda)`

`{\lambda}=5.878* 10^(-7)m`

Thus, wavelength of the wave is
`5.878* 10^(-7)m`
