Which light is used in newtons rings?
sodium light
Why extended source is used in the newtons ring experiment?
An extended source is used in the Newton's ring experiment to ensure that the light incident on the glass plate is coherent and uniform. This helps to produce clear and sharp interference fringes, which are essential for accurate measurements of the radius of curvature of the lens and the wavelength of light.
Why you use newtons ring to determine wavelength?
Newton's rings can be used to determine the wavelength of light because the diameter of the rings varies with the wavelength of the light being used. By measuring the diameter of the rings, the wavelength of the light can be calculated using the formula for constructive interference.
Why is an extended source used in newtons ring experiment?
An extended source is used in Newton's ring experiment to ensure uniform illumination across the entire surface of the plano-convex lens. This uniform illumination helps in producing a clear and distinct pattern of interference fringes, making it easier to measure the diameter of the rings accurately. Additionally, using an extended source reduces the effects of coherence length and ensures a consistent interference pattern, improving the reliability and precision of the experimental results.
What do you use newtons for?
Newtons are a unit of force. They are used in all sort of physics calculations.
What is a Canon ring flash used for?
A Canon ring flash is used by professional photographers to take macro photography. A normal flash at close up objects usually creates bad lighting, but a ring flash diffuses the light better.
How is the focal length of a spherical mirror affected when the wavelength of light used is increased?
The focal length of a spherical mirror is not affected by the wavelength of light used. It is determined by the mirror's radius of curvature and refractive index of the surrounding medium. The wavelength of light only influences the diffraction effects, not the focal length.
