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

Respuesta :

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

Answer:  [tex]5.878\times 10^{-7}m[/tex]

Explanation:  

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

[tex]\nu=\frac{c}{\lambda}[/tex]

where,

[tex]\nu[/tex] = frequency of the wave  =[tex]5.10\times 10^{14}Hz[/tex]

c = speed of light  =[tex]3\times 10^8ms^{-1}[/tex]

[tex]\lambda [/tex] = wavelength of the wave = ?

Putting in the values we get:

[tex]5.10\times 10^{14}=\frac{3\times 10^8}{\lambda}[/tex]

[tex]{\lambda}=5.878\times 10^{-7}m[/tex]

Thus, wavelength of the wave is [tex]5.878\times 10^{-7}m[/tex]
