Question

How much energy does a 2.4 × 1013 Hz wave have?

Answer 1

Energy =
`1.59* 10^(-20)` Joules

Step-by-step explanation:

We know,

Energy(E) carried by a wave =
`h* f`

where,

h - Planck's constant =
`6.626*10^(-34) Joule-seconds`

f - Frequency of the wave.

Given,

Frequency of given wave (f) =
`2.4* 10^(13) Hz`

Therefore from the above formula,

Energy carried by wave =
`h* f`

E =
`6.626*10^(-34)*2.4*10^(13)`

E =
`1.59* 10^(-20)` Joules

Therefore,

Energy carried by given wave =
`1.59* 10^(-20)` Joules
