What happened in newtons ring experiment if the glass plate is replaced by mirror?
if we use glass plate then ring's will be clear
Why do we observe the dark and bright colored frings in newton's ring?
the newton's rings are formed due to the phenomenon of thin film interference. here, the condition for constructive interference(the ring appearing bright) is that the optical path difference between interfering waves should be an integral multiple of the wavelength. the optical path difference is given by 2t-(l/2) if t is the thickness of the air film at that point and l is the wavelength of light. at the central point, the lens touches the surface so thickness t=0. thus the optical path difference is simply l/2, which is the condition for destructive interference, not constuctive interference. so the central spot has to always be dark.
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.

How do you calculate wavelength in Newton's ring experiment?
The condition for constructive interference in thin filmis,m = 0,1,2,....From equation (1) putting the value of t in the above equation we get,since n = 1 for air filmorFor first bright ring, m = 0For second bright ring, m = 1For third bright ring, m = 2Similarly, for Nth bright ring,m = N - 1Radius for dark ringThe condition for destructive interference in thin filmis,2tn = mλ m = 0,1,2,....By putting the value of t, we get,For air n = 1For i.e. point of contact.
Why is the angle of refraction zero in newton's ring exp?
The angle of refraction is zero in Newton's ring experiment because the incident light is perpendicular to the plane of the glass plate, so refraction does not occur. This allows for constructive interference between the incident and reflected light waves, leading to the formation of interference rings.
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.
If intermittent and difficult-to-diagnose wireless communication errors occur what might be the culprit?
Interference - If intermittent and difficult-to-diagnose wireless communication errors occur, interference might be the culprit.
Explain any one engineering application of interference due to thin films?
newtons rings
Does a 2004 Subaru have an interference engine?
yes, valve to piston interference is likely to occur if belt fails
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.
Does Packet Collisions occur in Token Ring Networks?
No, unless the ring is broken then collision can occur
Why do you take plano convex lens with a spherical surface of a large radius of curvayure in the newtons ring experimental set up?
In Newton's ring experiment, a plano-convex lens with a large radius of curvature is used to ensure that the interference fringes produced between the lens and the flat glass plate can be easily observed and analyzed. The large radius of curvature helps in creating distinct and well-defined interference patterns, which are essential for accurate measurement and analysis of the rings.
Why does the ring of fire occur where it does?
Because it wants to occur (:
If intermittent and difficult-to-diagnose wireless communication errors occur?
Interference.
What would occur when light is reflected from a rough or unpolished surface?
interference
What happens if you replace glass plate with plane mirror in newton ring experiment?
If you replace the glass plate with a plane mirror in the Newton's rings experiment, interference fringes will not be observed. The formation of Newton's rings depends on the light reflecting off the two surfaces of the air film between the glass plate and the lens, creating interference patterns. However, the mirror does not create the necessary conditions for interference to occur.
