sound ray meaning in Hindi

Examples

1. The principal task of geometrical acoustics is to determine the trajectories of sound rays.
2. The same laws of reflection and refraction hold for sound rays as for light rays.
3. Generally line source acoustic models trace sound ray bundles and calculate spreading loss along with ray bundle divergence ( or convergence } from refractive phenomena.
4. But humidity is not as prominent a factor in affecting low-frequency sound as the bending of sound rays ( or sound waves going in the same direction ) by wind and the temperature profile of the air.
