Light through a slit will only fall upon or illuminate a quite slight area.
Light moves in straight lines, following the laws of reflection and refraction. It can also travel through different mediums, such as air, water, and glass, at varying speeds.
The light moves from the source in a straight line to an object and then moves into the back of your eye to your retina.
Visible light moves through vacuum, and it also moves through anything that is gas, liquid or solid as long as what it moves through is not opaque. It has to be tansparent or translucent in order for light to move through it and be visible in some form on the other side.
All the directions
Because a straight line is the shortest path it can follow between two points. However a locally straight line may not be a globally straight line. This is how a gravitational field bends the path of light according to General Relativity.
The speed of light in a vacuum is constant everywhere. The speed of light in a particular medium depends on what the medium is. It moves slower in air than in a vacuum, and slower in water than in air.
The refraction of light means that although light travels in straight lines, when it moves from one substance into another, it can change direction. This happens because the wave changes speed as it travels between different types of materials.As a light wave travelsbetween diffrent clear substances, the light wave bends. When light passes one substance to another, the light changes direction.
Radiation moves in the form of electromagnetic waves or particles. Electromagnetic radiation, such as light and microwaves, travels in waves and does not require a medium to propagate. Particle radiation, such as alpha and beta particles, move in straight lines and can be absorbed or scattered by matter.
Far infrared radiation, like other forms of electromagnetic radiation, typically travels in straight lines in a vacuum. However, when it passes through different mediums, it can be refracted or scattered, which may alter its path. The degree of deviation depends on the properties of the medium it encounters. Overall, in open space, far infrared moves in straight lines.
As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or gas molecules
Light doesn't bend or curve. It only goes in straight lines, but you can change its direction using a shiny surface by reflection.Another way to change its path is to pass it from one transparent medium to another with a different molecular structure. The change in path as it moves from one medium to another is called refraction.
