A laser light appears as a bright, focused beam of light that is usually a single color such as red, green, or blue. It is coherent and does not spread out like the light from a flashlight, creating a sharp and visible line across surfaces.

What laser light like?

Laser light is monochromatic, meaning it consists of a single color/wavelength of light. It is also coherent, meaning the light waves are in phase with each other, resulting in a narrow beam with high energy density. Laser light is also directional and can be focused to a small spot, making it useful for various applications such as cutting, welding, and medical procedures.

Why can you see a light from a laser beam?

What is the difference between a ordaniry light and a laser?

The photons (units of light) in incoherent light fly around like, say pepper and water in a blender. The photon in LASER light all move in the same direction like soldiers marching together down a street. LASER light is 'Coherent' light. This means that a beam of coherent light can travel great distances without spreading out.
