The human eye can barely detect a yellow lings ( lamda=6000A ) that delivers 1.7xx10^(-18) W to the retina. The number of photons per second falling on the eye is nearest to

Estimate the following the following two numbers should be interesting. The first number will tell you why radio engieers do not need to worry much about a photons. The second number tells you why our eye can never "count photon" even in barely detectable light. (i) The number of photons emitted per second by a MW transmitter of 10kW power emitting radiowaves of length 500m. (ii) The number of photons entering the pupil of our eye per second corresponding to the minimum intensity of white light that we humans can precieve (~10^(-10)Wm^(-2)) . Take the area of the pupil to be about 0.4cm^(2) , and the average frequency of white light to be about 6xx10^(4)Hz. (h=6.6xx10^(-34)J)

Find the number of photons entering the pupil of our eye per second corresponding to the minimum internsity of white light that we humans can perceive (-10^(-10) Wm^(-2)) . Take the area of the pupil to be about 0.4 cm^(2) , and the average frequency of white light to be about 6xx10^(14) Hz .

The faintest sound the human ear can detect at a frequency of 1000 Hz correspond to an intensity of about 1.00xx10^-12(W)/(m^2) , which is called threshold of hearing. The loudest sounds the ear can tolerate at this frequency correspond to an intensity of about 1.00(W)/(m^2) , the threshold of pain. Detemine the pressure amplitude and displacement amplitude associated with these two limits. Take speed of sound =342(m)/(s) and density of air =1.20(kg)/(m^3)

The pupil allows light to pass through it and has a diameter of 2xx10^(-3)m. If minimum light intensity that should enter the eye is 1.8xx10^(-10) W//m^(-2) , then find the number of photon in visible range must enter the pupil to have vision. Wavelength of photon in visible range can be taken as 5,500Å .
