Two of the types of infrared light, ir-c and ir-a, are both components of sunlight. their wavelengths range from 3000 to 1,000,000 nmnm for ir-c and from 700 to 1400 nmnm for ir-a. compare the energy of microwaves, ir-c, and ir-a.

IR-A possess more energy than IR-C

Explanation:

Before anything, you need to understand that; the longer the wavelength a wave possess, the smaller the energy it has.

We have to use planck's equation and C=λv

where; C = Speed of light (3.0 x m/s)

            λ = wave length

            v = frequency

planck's equation =  E = hv

Equating the two equations; we get

E/h = C/λ

E = Ch/λ

where;

        h = planck's constant (6.63 x Js)

Comparing the energies of microwaves,

FOR IR-A

when

λ = 700nm = 700 x m

E = Ch/λ

E =  

E = 2.84 x J

when

λ = 1400nm = 1400 x m

E = Ch/λ

E =  

E = 1.42 x J

FOR IR-C

when

λ = 3000nm = 3000 x m

E = Ch/λ

E =  

E = 6.63 x J

when

λ = 1,000,000nm = 1,000,000 x m

E = Ch/λ

E =  

E = 1.99 x J
