What is the number of photons of light with wavelength 4000 pm which provide 1 Joule of energy?
What is the number of photons of light with wavelength 4000 pm which provide 1 Joule of energy?
Given: h = 6.626 × 10-34 Js,
c = 3 × 108 m s-1,
λ = 4000 pm = 4000 × 10-12 m = 4 × 10-9 m
Energy of photon (E) = hc / λ
= (6.626 × 10-34 Js) x (3 × 108 m s-1) / (4 × 10-9 m) = 4.969 x 10-17 J
i.e. 4.969 x 10-17 J is the energy of 1 photon
Therefore, 1 J is the energy

Calculate the wavelength, frequency, and wavenumber of lightwave whose period is 2.0 × 10-10 s.
Calculate the wavelength, frequency, and wavenumber of lightwave whose period is 2.0 × 10-10 s.
Wavelength, λ = (3 × 108 ms-1) / (5 × 109 s-1) = 6.0 x 10-2 m
Frequency, ν = 1 / 2.0 × 10-10 s = 5.0 x 109 s-1
Wavenumber, (? ) = 1 / (6.0 x 10-2 m) = 16.66 m-1
Upvote Calculate the energy of each of the photons which
(i) Correspond to light of frequency 3 × 1015 Hz
(ii) Have wavelength of 0.50 Å.
Calculate the energy of each of the photons which
(i) Correspond to light of frequency 3 × 1015 Hz
(ii) Have wavelength of 0.50 Å.
(i) Energy of photon (E) = hν, where h= Plank’s const, ν= Frequency
h= 6.626 × 10-34 J s ; ν = 3 × 1015 Hz = 3 × 1015 s-1
∴ E = (6.626 × 10-34 J s) × (3 × 1015 s-1) = 1.986 × 1018 J
(ii) Energy of photon (E) = hν = hc/λ, where λ= wavelength
h = 6.626 × 10-34 J s ; c

I would like to know the fee structure for studying agricultural economics for an ST category student who scored 75-80% in 12th grade.
Hello,
The fees for Agricultural Economics can vary by college. Government colleges usually charge between INR 15,000 and INR 1 Lacs per year, while private colleges can go up to INR 3 lakhs annually. Since you are an ST category student with 75-80% in 12th, you may qualify for scholarships and fee c
Upvote fee structured are on yearly base or of full coarse?
It's depends on college or university. Fee structure can be semester wise, yearly wise or one time fees payment for the full course. But mostly in India semester wise and Yearly wise fees are collected from the students.
Students must check the official website of their respective University or
