Question

Calculate the energy processed by a single proton of the each following types electromagnetic radiation:

a.6.32 x 10^20 s-1

b. 9.50 x 10^13 hz

c.1.05 x10^16 s^-1

#G10 Chemistry

Answer 1

a. 4.2 x 10⁻¹³ J

b. 6.3 x 10⁻²⁰ J

c. 7 x 10⁻¹⁸ J

Further explanation

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

`\large{\boxed{\bold{E\:=\:h\:.\:f}}}`

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

a.

`\tt E=6.626.10^(-34)* 6.32.10^(20)=4.1876.10^(-13)~J`

b.

`\tt E=6.626.10^(-34)* 9.50.10^(13)=6.2947.10^(-20)~J`

c.

`\tt E=6.626.10^(-34)* 1.05.10^(16)=6.9573.10^(-18)~J`
