The eyes of a reptille pass a visual signal what is minimum number of photons that must strike the receptor `(h = 6.6 xx 10^(-34))`?

The eyes of a reptille pass a visual signal to the brain when the visual receptors are struck by photons of wavelength 850nm. If a total energy of 3.15×10 −14 J is required to trip the signal, what is minimum number of photons that must strike the receptor (h = 6.6 xx 10^(-34)) ?

The eyes of certain member of the reptile family pass a single visual signal to the brain when the visual receptors are struck by photons of wavelength 850nm . If a total energy of 3.15xx10^(14)J is required to trip the signal. What is the minimum number of photons that must strike the receptor?

Frequency of photon having 66 eV energy will be…… (h=6.6xx10^(-34)Js)

Photons of wavelength 600 nm are emitted from a 60 watt lamp. What is the number of photons emitted per second ? Take h = 6.6 xx 10^-34 Js

The energy of a photon of wavelength 4000 Å is (use h=6.66xx10^(-34) J-s)

With what velocity must an electron travel so that its momentum is equal to that of a photon with a wavelength of 5000Å(h=6.6 xx 10^(-34)Js,m_(e)=9.1 xx 10^(-31) Kg)
