Question

How many Joules of energy are contained in a photon-with 2 = 496.36 nm?

Answer 1

• Wavelength=496.36nm

We know

`\boxed{\sf E=hv=(hc)/(\lambda)}`

`\\ \sf\longmapsto E=(6.626* 10^(-34)Js* 3* 10^8ms^(-1))/(496.36* 10^(-9)m)`

`\\ \sf\longmapsto E=0.004* 10^(-17)J`

`\\ \sf\longmapsto E=0.04* 10^(-16)`

`\\ \sf\longmapsto E=0.04eJ`
