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.
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.
yes. laser beams are just like light.
Polarized light is a type of light in which the electromagnetic waves vibrate in a single plane. This means that all the waves are oriented in the same direction, leading to a specific polarization state.
north
If you are standing precisely at the South pole, you can only travel north.
The North Pole is located at the northern most tip of the Earth. The only direction in which you can travel from the North Pole is south.
Only south!
You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.
A linear polarizer film is used to filter and control the direction of light waves. It works by allowing only light waves that are aligned in a specific direction to pass through, while blocking light waves that are oriented differently. This results in the transmission of light that is polarized in a single direction, which can reduce glare, improve visibility, and enhance contrast in images.
That would be south.
North
Antarctic Bottom Water can only travel north.
