No, Sound is a pressure wave not a linear wave, the waves radiate spherically from their point of origin.
Also as a pressure wave, it travels in a medium and if that medium is moving the sound wave propagation can be modified by that movement (bent).
They also behave like sea waves impinging on a headland and can be bent round objects in their path in complex ways.
To remember this think of you are looking directly at a building a car crash happens behind this building. You know this from the sound produced that can travel in all directions past the building. You cannot see it because as light dose not bend under normal circumstances and will only travel in straight lines. Even if reflected using a combination of mirrors it still travels in straight lines.
Theoretically they doNot theoretically, they do travel in waves.See my answer here:Do_light_waves_travel_in_straight_paths_called_rays
Yes there is. Your shadow is the simplest evidence that light travels in straight line. A solar eclipse is also evidence that light travels in straight lines, as is the fact that you cannot see around corners unless you use a mirror.
Yes, if there were no force of the Sun's gravity, planets would travel in a straight line due to the concept of inertia, which describes an object's tendency to continue moving at a constant velocity in a straight line unless acted upon by an external force.
The Mercator projection does that.
yes
The magnetic lines are always circular & emerging from north & entering in the south pole of magnet outside it. they are never straight.
no
cuz it does
the travel in straight lines because of the atomsphe
Isaac Newton proposed that light consisted of particles that travel in straight lines through space.
Earthquake P-waves don't travel in straight lines, they travel in like a circle after the earthquake has struck. These P-waves arrive first during an earthquake.

The phenomenon where light waves travel in straight lines is called rectilinear propagation. This means that light travels in a straight path unless it encounters a medium that causes it to change direction.
Light rays always travel in straight lines in a medium with a uniform refractive index. This is known as the principle of rectilinear propagation of light. However, in mediums with varying refractive indices or when interacting with surfaces, light rays can bend, reflect, or refract.
Light rays travel in straight lines due to the principle of the shortest path, known as Fermat's principle. Light travels along the path that minimizes the time it takes to travel from one point to another. This results in light rays following straight lines in a uniform medium.
Yes, light in a vacuum typically travels in straight lines in a phenomenon known as rectilinear propagation. This means that light will travel in a straight line unless it encounters a medium that can bend or scatter its path, such as a prism or particles in the atmosphere.
