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.
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.
Theoretically they doNot theoretically, they do travel in waves.See my answer here:Do_light_waves_travel_in_straight_paths_called_rays
Light cannot travel from New York to Tokyo, at least not without a seriously large number of mirrors, since light travels in nominally straight lines.
Light travels in a straight line. The path of light can be bent by very massive objects because they actually bend space.
Ibn al-Haytham (965 in Basra - c. 1040 in Cairo) a Muslim scientist, proved that rays of light travel in straight lines, and carried out various experiments with lenses, mirrors,refraction, and reflection. He was also the first to reduce reflected and refracted light rays into vertical and horizontal components, which was a fundamental development in geometric optics.Book of Optics.(Ibn al-Haytham)
yes
Transparent
It does not, it travels as a wave
NORTHAmended answerLight travels in straight lines.
Light travels faster than air. Its beam are straight so that it travels through holes.
No it doesn't. Sound travels in waves, but light tavels in straight lines.
Yes..according to rectillinear propagation of light must travell in straight line...it also travells in the form of wave
All electromagnetic radiation from VHF and higher frequencies (including visible light) travels only in straight lines. However these frequencies will reflect off certain surfaces, one surface that visible light reflects off is a mirror, which if properly arranged can be used to see around corners.
It travels in straight lines, However light cannot pass through walls, such as sound.
In straight lines (well, "geodesic" might be a better term), and at the speed of light in the medium they're in.
