Here's the example that illustrate what you just asked. I will be using this example from astronomy. When you look up the sky to the stars, you are literally seeing into the past. The distance from you to the star you are looking at is x lightyears away. Lightyear is distance light travles in 1 year. So if a star is, say 100 lightyears away from you, then you are seeing the state of the star that much time ago.
What else can I help you with?
Which waves can be separated into different wavelengths of colored light?
Visible light waves can be separated into different wavelengths of colored light. This can be achieved using a prism, diffraction grating, or other optical devices that disperse light based on its wavelength, resulting in the familiar rainbow spectrum.
What type of light bulb converts ultraviolet waves into visible light?
A fluorescent light bulb converts ultraviolet waves into visible light using a phosphor coating inside the bulb. When the UV light hits the phosphor coating, it emits visible light.
Light waves are classified as what waves?
Optical light waves are "Electromagnetic" waves. The colour seen is dependent on the wavelength of the light. Electromagnetic waves are transverse waves where the oscillation is 90 degrees to the direction of travel (unlike sound waves which are longitudinal).
Where do light waves originate?
Light waves originate from a light source, such as the sun, a light bulb, or a laser. When an object absorbs energy, it can emit photons, which are the elementary particles of light that travel as electromagnetic waves.
Light and sound waves have many similar properties however light waves are what while sound waves are what?
Light waves are eletromagnetic waves and sound waves are mechanical waves. Additionally, a light wave is a transverse wave that does not require a medium through which to travel. Sound waves, on the other hand, are longitudinal waves where the source transfers the mechanical energy of the sound wave into the medium so it can travel.
How do you block light waves?
Light waves can be blocked by using opaque materials that do not allow light to pass through, such as walls, curtains, or blinds. Another method is to use specialty coatings or films on surfaces to absorb or reflect light waves. Additionally, light waves can also be blocked by creating barriers or obstructions that prevent the direct passage of light, such as building structures or using physical objects to cast shadows.
What is electronic waves that people can see?
Visible light.
What is the fastest way to send information using sound waves light waves or water waves?
Light waves are the fastest way to send information, as they travel at the speed of light in a vacuum (c = 299,792,458 meters per second). Sound waves and water waves travel much slower, with sound waves traveling at about 343 meters per second in air and water waves traveling at varying speeds depending on the medium.
Which waves can be separated into different wavelengths of colored light?
Visible light waves can be separated into different wavelengths of colored light. This can be achieved using a prism, diffraction grating, or other optical devices that disperse light based on its wavelength, resulting in the familiar rainbow spectrum.
What is radio astromony?
astronomy using radio waves, rather than visible light. visible light and radio waves are essentially the same, only radio waves have a much longer wavelength. not everything emits light in the visible band, many otherwise invisible objects can only be detected using extreme wavelengths.
The intensity of light waves is a measure of what?
The intensity of light waves is a measure of the energy carried by the waves. It is proportional to the square of the amplitude of the waves. The intensity of light waves determines how bright the light appears to us.
What is distomate?
Distomat is an instrument used to measure distance using light and radio waves.
Are radio waves a form of sound or light?
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.
What type of light bulb converts ultraviolet waves into visible light?
A fluorescent light bulb converts ultraviolet waves into visible light using a phosphor coating inside the bulb. When the UV light hits the phosphor coating, it emits visible light.
How are ultraviolet waves different from light waves?
Ultraviolet waves are smaller than light waves.
Are sound waves stronger than light waves?
No because light waves are stronger and brighter and sound waves are light and dull
Do all light waves emit radiation?
Light waves do not emit radiation, light waves are radiation.
