If the energy of a photon of light is 3.37 x 10–19 J, what is the frequency of the light? A. 1.12 x 10–27 s –1 B. 8.90 x 1026 s

Dmitry [639]

Answer:

The appropriate alternative is option C " $5.09\times 10^{14} \ s$ ".

Explanation:

The given value is:

Energy of photon,

E = $3.37\times 10^{-19} \ J$

As we know,

h = $6.626\times 10^{-34} \ Js$

Now,

The frequency of the light will be:

⇒ $E=hv$

On substituting the given values, we get

⇒ $3.37\times 10^{-19}=6.626\times 10^{-34}\times v$

On solving, we get

⇒ $v=5.09\times 10^{14} \ s$
