How do I determine what wavelength to use in petroleum product to determine ultraviolet absorption?

To determine UV-absorption you need to use UV-light. And there's a defined wavelength for UV-light.


What is the order of the colours obtained in newtons ring experiment if illuminated with white light?

The centre spot will be dark even when we use white source. As the radius of the ring is directly proportional to the square root of the wavelength, the violet being the shortest wavelength will come first and red will be the last as its wavelength is the longest in the visible region. Any how we cannot get sharp coloured rings around the black spot. Instead overlapping occurs and just multicoloured rings can be seen.


To determine the speed of a wave what formula would you use?

You can determine the velocity of a wave when given the frequency and the?

You can use the equation v=fw. that is velocity (in meters per second) equals the frequency (in hertz) times the wavelength (in meters). so you can find the velocity of a wave with the frequency and the wavelength.

How can newtons rings be used to find the radius of curvature?

The expression for the radius of the nth dark ring is given as rn2 = n R l Here l is the wavelength of monochromatic source. R- the radius of curvature of the plano convex lens n is the order of the ring. Theoretically we can get value of R knowing other quantities. But practically we use the following expression R = r n+m 2 - r n 2 / m l This would reduce the error due to non symmetry of the smaller rings.
