Energy from the sun is received on the earth at the rate of `9J//cm^(2)//`minute. The average wavelength of solar light is taken as 5500 Å. How many photons are received on the earth per `cm^(2)` per minute? `[h=6.6xx10^(-34)J-s]`

Energy from the sun is recived on earth at the rate of 2 cal per cm^(2) per min. If avergae wavelength of solar light be taken at 5500 A then how many photons are recived on the earth per cm^(2) per min ? (h =6.6 xx 10^(-34)J-s, 1cal = 4.2J)

Energy from the sun is recived on earth at the rate of 2 cal per cm^(2) per min. If avergae wavelength of solar light be taken at 5500 A then how many photons are recived on the earth per cm^(2) per min ? (h =6.6 xx 10^(-34)J-s, 1cal = 4.2J)

How many photons are received on earth per cm^-2 per hour if the energy from the sun reaching on the earth is at the rate of 2cal cm^(-2) min^(-1) and average wavelength of solar light be taken as 5500Å. Use h=6.6xx10^(-34)J , c=3xx10^8ms^(-1) and 1cal =4,2J

How many photons of light with wavelength 400 nm can provide 1 J energy? [h=6.626xx10^(-34)J*s]

Earth receives energy at the rate of 2.5"cal /cm"^2 min . Calculate the number of photons received on the Earth. Per cm^2 per minute if the average wavelength of solar light is 500 nm. Take 1 calorie = 4.2 J

How many photons of wavelength , 50 Å are required to produce 0.2 J of energy ? ( h = 6.626 xx 10^(-34) J *s )

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

The energy of photon of reddish light having wavelength 660nm is ( h=6.6xx10^(-34)Js )
