angle of divergence मीनिंग इन हिंदी

The angle of divergence is very roughly equal to the wavelength divided by the initial diameter of the beam.
Outgoing light beams diverge from the prism, giving two polarized rays, with the angle of divergence determined by the prisms'wedge angle and the wavelength of the light.
In the UK, where the angle of divergence is shallower than 1 in 8 ( center-line measure ) a switched diamond will be found rather than a passive or fixed diamond.
A simple solution would be to have a gamma ray absorber absorbing all the gamma rays moving in the forward direction, delivering part of the thrust; and letting the rest be emitted without any deflection ( therefore with an angle of divergence of 180?), which cuts in half the ( average ) useful momentum of the gamma rays, resulting in the specific impulse being less of what it would be in the idealized case.
:: : But the beam is focused-sending at 2380 MHz with a 305 m aperture gives you roughly an angle of divergence ( or rather half-angle ) of a = c / ( 2.38 * 10 9 Hz ) / 305 m, and the fraction of the unit sphere which is illuminated by the beam is approximately b = a 2 * pi / ( 4 * pi ) = 4.26 * 10-8.
