WebThe light from a laser is very clear evidence that light can be viewed as a ray that travels in a perfetly straight line. Notice in the diagram above that we represent a ray of light as a straight line with an arrow to indicate its direction.

WebVisible light. Visible light is the light we can see. It is used in fibre optic communications, where coded pulses of light travel through glass fibres from a source to a receiver. Visible light, together with ultraviolet radiation and X-rays, is generated when the electrons in an atom lose energy. Ultraviolet radiation WebDiffraction is observed of light waves but only when the waves encounter obstacles with extremely small wavelengths (such as particles suspended in our atmosphere). Diffraction of sound waves and of light waves will be discussed in a later unit of …

Each color of light has a different wavelength. For example, blue light has a shorter wavelength than red light. Sunlight—and the typical light from a lightbulb—is made up of light with many different wavelengths. list of bruce springsteen albumsWebHome; What We Do.

They do not need a substance to travel through, but they can travel through transparent and translucent substances. Light waves cannot travel through opaque substances- they get reflected or absorbed.
