Question

Long-wavelength infrared cameras detect infrared radiation with a wavelength of 1.0 x 10-5 meters. How much energy is in these waves? Talas​

Answer 1

Answer: The energy of the infrared radiation is
`19.8* 10^(-21)J`

Step-by-step explanation:

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

`E=(hc)/(\lambda)`

E= energy

`\lambda` = wavelength of the wave =
`1.0* 10^(-5)m`

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

c = speed of light =
`3* 10^8m/s`

`E=(6.626* 10^(-34)Js* 3* 10^8m/s)/(1.0* 10^(-5)m)`

`E=19.8* 10^(-21)J`

Thus energy of the infrared radiation is
`19.8* 10^(-21)J`
