This question is about refraction. (a) The diagram below shows a ray of monochromatic light incident on the boundary between two media. The dotted line is the normal to the boundary. normal medium 1 -boundary medium 2 The refractive index of medium 1 is n, and that of medium 2 is n, and n,>n,. The ray is incident at an angle to the normal that is less than the critical angle. (i) Explain what is meant by critical angle. (ii) On the diagram above, draw lines to show the paths of the ray after it is incident on the boundary. (b) Derive a relationship between n,, n, and the critical angle 6,.

Light passes through two slits separated by 0.01mm. The first order maximum is located at an angle of 30 Degreeson a screen 1 m away from the slits.(a) What is the wavelength of the light?(b) Find the distance between the 1th and the 2nd order maxima.Draw the diagram and indicate the locations of the 1th and 2nd order maxima.

For light that originates within a liquid and strikes the liquid/air interface, the critical angle is 37°. What is Brewster's angle for this light? Number i Units

A medium was replaced with another having twice the index of refraction of the first one. What will be the value of the new critical angle? Group of answer choices The angle is halved. The sine of the angle is halved. The sine of the angle is doubled. The angle is doubled.
