I presume you asking, "How can an atom of size about 1 angstrom absorb a photon whose wavelength is 5000 angstroms? Wouldn't the photon be too large for that atom?"
The paradox is resolved in this way: the instant you start to discuss electro-magnetic radiation as a photon instead of a transverse electro-magnetic wave, then you negate the wave-length aspect of the light. Instead, you view light as a collection of photons -- particles whose "size" (if that word has meaning) is point-like -- with a specific energy instead of specific wavelength.
A photon is NOT a snake-like wave, vibrating like a rubber band, with a length at least that of its wave-length, as it moves through a medium. A photon is a point particle with a specific energy.
You can describe light as a EM wave with a wave-length OR as a collection of point particles. You can NOT do both at the same time. Light exhibits the characteristics of one OR the other, but NEVER both.
here, energy E = hf where h = plank const, f = c*wavelenght c =3*10^8m/s h = 6.626*10^-34 then simplyfying got ans....
A sound wave with a frequency of 125 Hz has a wavelength of 40 meters (speed = frequency x wavelength). At a speed of 5000 m/s, this sound wave would have a period of 0.08 seconds (period = 1 / frequency).
The radio waves used by radio-controlled clocks and wristwatches operate at a frequency of 60 kHz, which corresponds to a wavelength of approximately 5000 meters. This wavelength allows the signal to penetrate buildings and obstacles, ensuring accurate time synchronization.
Period = Wavelength/Speed = 10mm/50,000 mm/s = 1/5000 s or 0.0002 seconds
E = hv where that "v" is actually supposed to be the Greek letter nu, standing for frequency. So just convert the wavelength to frequency and multiply by Planck's constant and you'll have your answer.
60Hz has a wavelength of 5000 meters.

there is over 5000 speciesThey absorb water and you can release it by squeezing it
The absence of peaks in that range could indicate that the material being analyzed does not strongly absorb or emit light within that wavelength range. It could also suggest that the material has a smooth or continuous absorption or emission profile in that region.

Babolat Extra Sweet spot. Rs.5000 and it does not need Shock absorb. I think this is cheapest and best in Babolat.
