hello Ive tried everywhere to get the answers to these questions so I know if im doing them right and I'm running out of time to hand them in... please if you could help it would be greatly appreciated!!!
1. The antenna length for best reception of radio-frequency transmissions is normally half the wavelength of the signal being received. What antenna length (in m) is best suited for reception of a TV station that broadcasts at 232.7 MHz?
2. Calculate the smallest increment of energy (that is, the quantum of energy in J) that an object can absorb from light whose wavelength is 527nm?
3. A detector receives a 1.506e-16 J signal from photons whose wavelength is 569nm, how many photons were detected?
4. A hydrogen atom in its ground state absorbs a photon of wavelength 102.5 nm. To which higher energy state will it be excited?
