This is not only true of all forms of light waves but all electromagnetic waves as well. Diffraction is the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. It travels at the equivalent of 300,000 kilometers per second. Light travels in a straight line, but the waves can be refracted, reflected, or diffracted. Image Credit: stux, Pixabay Light Wave Properties Light is massless, meaning that it can travel through a vacuum, which is why we can see light sources from millions of miles away in the sky. Visible Light – Visible light rays are the only electromagnetic waves that can be seen by the human eye, and different wavelengths are seen by the human eye as different colors.ĭepending on the frequency of light waves, some can travel through solid objects, while others can travel through liquid and gases.They are generated by objects like black holes and supernova explosions, and they are used in radiotherapy and, in some cases, sterilization. Gamma Rays – Gamma rays have the most energy of any light wave.They are most commonly used in hospitals to view bones and skeletal structures. I think it´s C from what the other person tried to explain. A reflected sound wave changes direction as it passes through an opening. X-Ray – X-Rays are invisible to the human eye and cannot be felt, but they can pass through solid objects, including the human body. A diffracted sound wave bounces back to the place of origin.It is present in sunlight and projected by tanning beds. Ultraviolet – Ultraviolet, or UV, light is another form of light wave that is invisible to the human eye.Infrared cameras enable viewers to be able to “see” objects according to the amount of infrared that object radiates, effectively letting us see images even in the dark. Infrared Light – Infrared is not visible to the human eye, and it can be felt as heat.Microwaves – Microwaves are also used for communication and in radar but are most commonly seen in cooking thanks to their ability to generate heat. However, radio waves are a form of light wave and are also used in telecommunications and the sending of TV signals. Sound and water waves are mechanical waves meaning, they require a medium to travel through. Light, sound, and waves in the ocean are common examples of waves. Waves transfer energy from one place to another, but they do not necessarily transfer any mass. Radio – Most people think of sound when they hear the term “radio wave” because we listen to sounds coming from the radio. A wave is a disturbance that travels or propagates from the place where it was created.
