You want to find the number of photons (radio frequency ones) emitted per second.Jacob87411 said:
No. This equation will give you the energy that is released in one photon.Jacob87411 said:
You do not need the speed. You need Planck's Constant.Jacob87411 said:
So how many photons are produced in one second?Jacob87411 said:
Personally I get a rather large number (which is too be expected) but should it be this (2.9 x 1030 photons) big?Andrew Mason said:
Was it the same as my number?Jacob87411 said:
It was in white.Jacob87411 said:
It is that big. At 1000 km, the intensity would be about 2 x 10^17 photons/m^2 per second. And that is just a measly radio antenna. You can see why a quasar can still provide detectable radio signals on Earth despite being billions of light years away.The Bob said:
You can. So much for telescopes that can detect a few photons of light, use radar discs.Andrew Mason said:
To convert Joules to Quanta, you can use the formula E = h*c/λ, where E is energy in Joules, h is Planck's constant, c is the speed of light, and λ is the wavelength in meters.
Joules and Quanta are both units used to measure energy. Quanta is a unit specific to quantum mechanics, while Joules is a more general unit used in classical physics. One Joule is equal to 6.242×10^18 Quanta.
Yes, you can convert Quanta to Joules using the same formula as converting Joules to Quanta. Simply rearrange the formula to solve for E (energy in Joules).
The conversion from Joules to Quanta represents the relationship between energy and electromagnetic radiation. It shows how energy is quantized and can only exist in discrete amounts, as described by the quantum theory.
Converting between Joules and Quanta allows us to understand and analyze energy at the quantum level. It helps us to better understand the behavior of particles and their interactions with electromagnetic radiation, and is crucial in fields such as quantum mechanics and particle physics.
