Calculate momentum of photon. Frequency associated with the photon is `5 xx 10^(13)` Hz. Given `h6.6 xx 10^(-34)` Js and `c=3 xx 10^(8) ms^(-1)`

Explanation

Frequency of photon = `v = 5 xx 10^13 Hz `
`h = 6.6 xx 10^(-34) Js`
`h = 6.6 xx 10^(-34)Js`
`c = 3 xx 10^8 ms^(-1)`
Momentum of photon = `P = ? `
`P = (hv)/c`
`P = (6.6 xx 10^(-34) xx 5 xx 10^13)/(3 xx 10^8)`
`= 2.2 xx 5 xx 10^(-29)`
`= 11.0 xx 10^(-29)`
`P = 1.1 xx 10^(-28) kg ms^(-1)`
