What happens when light strikes a mirror?
When light strikes a mirror, it is reflected back at the same angle it hit the mirror, following the law of reflection. The angle of incidence (the angle at which the light beam strikes the mirror) is equal to the angle of reflection (the angle at which the light beam bounces off the mirror).
Explain how a beam of light passing through a diffuse cloud may give rise to both absorption and emission spectra?
When a light passes through a diffuse cloud, part of the light will be reflected, part will be absorbed, and the rest will pass through depending on the density of the cloud and the energy of the light.The light's energy can be expressed by: E = h(Planck's constant)*nu(frequency)
When a beam of alpha particles passes between two electrically charged plates - which plate is the beam deflected toward?
The beam would be deflected to the negative plate, as alpha particles are Helium nuclei and are positively charged.
How does a prism reflects colors?
A prism reflects colors by bending and separating white light into its individual components due to the process of refraction. This separation occurs because each color of light has a different wavelength and is refracted at a slightly different angle, resulting in the spectrum of colors being visible.
What is another name for the triple beam balance?
A common alternative name for the triple beam balance is the triple beam scale.
Explain what happens when a beam of light passes through a gold solution?
A part of this light is absorbed.
Explain What happens when a beam of light passes through a colloidal solution and why?
When a beam of light passes through a colloidal solution, the light scatters off the suspended particles in the solution in all directions. This scattering of light is known as the Tyndall effect. The intensity of the scattered light depends on the size of the particles in the colloidal solution.
What happens to a laser beam when you pass it through a silt?
When a laser beam passes through a silt, the particles in the silt scatter the light, causing the beam to lose coherence and intensity. This effect is known as light scattering, and the laser beam may appear diffused or weakened as it passes through the silt.
A beam of light can be seen as it passe through a?
a beam of light can be seen if it passes through reflective material.
What happens to the beam of light when it hits the water?
When a beam of light hits water, it can undergo refraction, which causes it to change direction due to the change in speed between air and water. Some of the light may also be reflected off the surface of the water.
If a spotlight is shown onto a still lake describe what happens to the beam of light?
The light if directed in the water will bend.
What happens to a beam of light when you put it through a con cave lens?
Alot happens when you put a lense into a beam of light.
What is the size of the light beam that passes though a microscope regulated by?
condenser
Can a beam of light be seen as it passes through a compound?
No, a beam of light passing through a compound is not visible unless there are particles or impurities present that scatter or reflect the light. In a pure compound, light passes through without any significant interaction, making it invisible to the naked eye.
When a light beam passes through a medium the beam can change direction and appear to bend and the process is called what?
Refraction.
What is the light beam size regulated by?
The size of a light beam is regulated by the aperture of the lens or the diameter of the opening through which the light passes. A smaller aperture will create a narrower and more focused beam of light, while a larger aperture will create a wider beam.
Why do lasers appear in smoke or water?
In order to be seen, light must reach the eye. Since laser light is coherent, it travels only along its line of propogation, so there is no light to be viewed from the side of the beam. However, when a laser beam passes through fog, it is reflected off of tiny particulate droplets of water in the fog (or smoke particles in smoke), so is diffused in all directions and can be observed. In order to be seen passing through water, there must be suspended particles in the water from which the light can be reflected. The beam should not be visible as it passes through perfectly pure water.
