You mean "can light waves travel in nonstraight lines?"?
Yes, if they are diffracted or pass through different materials. Gravity can also affect light waves and curve them.
yes
Seven.
Light does not always travel in st. lines. it bends arround an obstacle if its size smaller than the wavelength of the light wave.This is called diffraction
Light does not travel further along power lines. What phenomenon are you describing?
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.
Lines of least travel time.
because ,light travel in stright lines.
Isaac Newton proposed that light consisted of particles that travel in straight lines through space.
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.

Light can travel in wavy lines, as it behaves like a wave with characteristics such as interference and diffraction. This wavelike nature allows light to exhibit phenomena such as reflection, refraction, and dispersion.
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.
