Light typically travels in a straight line through a uniform medium. However, if the medium's density changes, light can be refracted and its path curved. Additionally, light can be reflected, diffracted, or scattered depending on the properties of the medium it is passing through.
When light travels through a medium, it travels in a straight line until it encounters a boundary between two different media, where it may refract, reflect, or scatter. The speed of light may change depending on the medium it is traveling through, which can affect its direction and intensity.
Waves do not travel in a straight line. They oscillate or move up and down as they propagate through a medium like air, water, or solid materials. This results in a wave pattern that can be curved or exhibit other complex behaviors.
Light will continue in a straight line through the medium unless it encounters a boundary or a change in the medium's properties. It may be absorbed, reflected, or refracted depending on the characteristics of the medium.
Line travels in straight lines, under the principle of least time, aka Fermat's Principle. Light can be refracted at the boundary between two media meaning the path is bend but both parts of the path remain straight lines. Technically, light follows a space-time geodesic which might be curved, but locally this is too small to detect.
In a compression wave, the medium is displaced in the same direction that the wave is travelling. This means that the particles of the medium move closer together and then farther apart as the wave passes through.
Air is the medium (if you are talking about something travelling through it).

Travelling through a medium that is optically less dense. Vacuum is best.
The velocity of light (and other electromagnetic waves) depends on the medium through which it is travelling.
towards the normal
In a compression wave, the medium is displaced in the same direction that the wave is travelling. This means that the particles of the medium move closer together and then farther apart as the wave passes through.
The medium through which it is propagating. For exampl if the sound waves are travelling in air they will move slower than those travelling through a wall speed of sound in solids > speed of sound in liquids > speed of sound in gases
away from the normal
travels through a uniform medium
