NORTHAmended answerLight travels in straight lines.
It travels in straight lines, However light cannot pass through walls, such as sound.
A ray of light can travel in any direction, so an infinite number.
scattering
The light waves bounce off the surface and travel in a new direction
That is correct. Polarization is possible only when the direction of vibration is perpendicular to the direction of the wave travel, such is in light. In sound waves, the direction of vibration (compression) is the same direction as the direction of the travel of the sound wave, and therefore polarization is not possible.
when two light waves of same frequency travel approximately in the same direction have a phase difference that remain constant w.r.to time

The light from our sun radiates out in all direction as the sun is ball-shaped. The part of light that strikes the earth, forming daylight, is spread over a wide area of the earth that happens to be facing towards the sun at the time. This means that light doesn't travel in a single direction. A laser beam is an example of a concentrated beam of light travelling in a single direction.
It travels around the sun in the same direction as the other planets. This is considered the "positive" direction.

Rarefactions decompressions travel in the same direction, because sound are longitudinal waves.
Light travels in the direction it was emitted. Light cannot steer itself towards any particular object.
Photons oscillate (vibrate) along an axis that is perpendicular to the direction of the photon's travel. Photons are responsible for all electromagnetic radiation, including visible light, invisible light (infrared and ultraviolet), X-rays, radio waves, and magnetic waves. . When all photons in a beam of light oscillate in same direction, that is called polarized light.
