What is the principle work of the filter when white light incident on it and laser incident too?
When white light is incident on a filter, it selectively absorbs certain wavelengths of light and transmits others based on its design. With a laser, the filter will either transmit or reflect the specific wavelength of the laser light, depending on its properties. In both cases, the filter's role is to control the passage of light based on its optical characteristics.
What are laser rangefinders used for?
A laser rangefinder uses a laser to determine the distance to an object. The principle used is the time of flight principle based on the speed of light.
What is the working principle of a laser?
A laser works by emitting a concentrated beam of light through a process called stimulated emission, where photons are amplified and aligned to create a powerful and focused beam of light.
What is the purpose of filter in planks constant experiment?
The purpose of the filter in the Planck's constant experiment is to ensure that only a specific wavelength or frequency of light is incident on the photosensitive surface, which helps in determining the relationship between the energy of the incident light and the resulting photoelectric effect. By using a filter, researchers can control the quality of the light being used in the experiment and focus on studying the effects of light with specific characteristics.
Why do different laser beams exhibit varying colors, such as blue and red, based on the principle of wavelength"?
Different laser beams exhibit varying colors, such as blue and red, based on the principle of wavelength because the color of light is determined by its wavelength. Shorter wavelengths, like those of blue light, appear blue to our eyes, while longer wavelengths, like those of red light, appear red. Laser beams produce light of specific wavelengths, which is why they can appear as different colors.
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
Is a laser artificial sunlight?
No. Laser light is artificial light, but it is not sunlight.
What dose laser stand for?
Light amplification by stimulated emission of radiation(LASER or laser)
What does abbreviation LASER stand for?
Light Amplification by Stimulated Emission of Radiation (LASER or laser.)
What is the scientific principle involved in a laser?
A laser operates based on the principle of stimulated emission of radiation. Stimulated emission occurs when a photon interacts with an excited atom, causing the atom to emit another photon that is identical in wavelength, phase, and direction to the first. This process leads to the coherent and intense light output characteristic of lasers.
What are lasers used for?
A laser rangefinder uses a laser to determine the distance to an object. The principle used is the time of flight principle based on the speed of light.
An ideal polarizing filter transmits 50 of the incident non polarized light. Why is this so?
Unpolarized light has electromagnetic waves vibrating in all directions perpendicular to the direction of propagation. A polarizing filter only transmits light that is polarized along the same axis as the filter's axis. (Note that a polarizing filter also partially allows some orientations through that have some component of its axis along the same axis as the filter). The transmitted light thus constitutes half of the incident unpolarized light.Think of it like this: unpolarized light is like a rope vibrating up and down and a rope vibrating side to side. A polarizing filter is like "slots." If the slots are up and down, only up and down vibrations can get through. The other half- the side to side vibrations- are blocked.
