Because the amount of bending is too small for your eye/brain system to detect.
During typical conditions of atmospheric refractivity gradient, a horizontal beam of
visible light can be expected to refract vertically by about 14 feet in 10 miles, by a
little less than 2 inches in one mile, and by about 0.0000086 inch in the 12-foot
width of the room.
h = (d1d2) / (1.5 K)
d1, d2 in miles
K = 6/5 for light
Because there is not much that the light can reflect off - maybe a few dust particles.
Fill the room with particles, say steam or smoke and you will see the beam.
Because light is only refracted when it passes into a more or less dense medium. As the density of air is reasonably constant, refraction is not easily observable in your average room.
Neither. it is getting a flashlight wet. The beam of light from the flashlight will refract when exiting the tank (and refract several times if going through a glass wall of the tank). If the tank wall is smooth enough of a material with enough of a difference in optical density and the flashlight beam hits the wall at a small enough angle there will be total internal reflection.
A prism refracts light, and a mirror reflects light.
The flashlight does.
Yes, hand lens reflect light.
A flashlight may not light if there is no energy source or in this case battery.
light travels in straight path and when speed of medium in which light travels change then it refract due to change in speed light rays bend and refract
To support that light travels in a straight path, take a flashlight and turn it on. Then, you could point it in any way around a room, upside down, angled, tilted, etc., and where ever you shine the flashlight, the ball of light is always straight across from the flashlight.
Through cold air
In a straight line. At the speed of light.
To prove that light travels very quickly, first, you need a flashlight. Because a flashlight is giving off light into a focused circle, it is still light. If you turn on the flashlight, as soon as you hit the switch or button, the circle of light at the other end shining on something appears instantly. You cannot catch the light in motion towards the surface the light is being aimed onto, and because light travels so fast, that is why you cannot see the light between the flashlight and the light on a surface.
Because light travels at different velocities, and various colors of light also travel at different speeds in optical media.
Neither. it is getting a flashlight wet. The beam of light from the flashlight will refract when exiting the tank (and refract several times if going through a glass wall of the tank). If the tank wall is smooth enough of a material with enough of a difference in optical density and the flashlight beam hits the wall at a small enough angle there will be total internal reflection.
It refracts four times.

Yes, it does refract light.
No, opaque substances can NOT refract light. It is impossible to refract light if it is blocking it's path.
