Does a laser change direction in mid air?
No, a laser beam travels in a straight line through air unless it reflects off a surface. The direction of a laser beam can be altered by using mirrors or prisms, but it does not change direction on its own in mid-air.
Why can't we see a laser beam?
Laser beams are typically invisible to the human eye because they emit light in a very focused and narrow wavelength, often in the infrared spectrum. The lack of scattering and diffraction in laser light prevent it from being visible unless it interacts with particles or surfaces in its path.
How can we see a lazer beam?
A laser beam is usually invisible to the naked eye. However, if there are particles or dust in the air, the beam may scatter the light and become visible as a thin line. Another way to see a laser beam is to use special goggles or a camera that can detect the specific wavelength of the laser.
How do you demonstrate that lights travel straight path?
One way to demonstrate that light travels in a straight path is by using a laser pointer. When you point the laser at a wall, the light beam will create a straight line from the laser to the wall. This shows that light travels in straight lines unless it encounters an obstacle or is refracted by a medium.
