A plano-convex lens with radius of curvature R = 3.0 m is in contact with a flat plate of glass. A light source and the observer’s eye are both close to the normal, as shown in Figure 24.8a. The radius of the 50th bright Newton’s ring is found to be 9.8 mm. What is the wavelength of the light produced by the source?

The pupil of an eagle's eye has a diameter of 6.0 mm. Two field mice are separated by 0.010 m. From a distance of 201 m, the eagle sees them as one unresolved object and dives toward them at a speed of 16 m/s. Assume that the eagle's eye detects light that has a wavelength of 550 nm in vacuum. How much time passes until the eagle sees the mice as separate objects? t = i

Light originating in air is normally incident on a thin film of thickness 150nm with index of refraction n₁ = 1.5 that lies on top of a material with index of refraction n₂ = 1.2, as illustrated. nAir n1 n2 Determine the longest wavelength of light that is maximally reflected. O 450nm O 900nm O 600nm O 300nm

The lens of a telescope has a diameter of 25 cm. You are using it to look at two stars that are 2 × 10 17 m away from you and 6 × 10 9 m from each other. You are measuring light with a wavelength of 700 nm. As the light goes through the lens, it diffracts. a. Is it possible, using this telescope, to see the two stars as separate stars?  b. What is the minimum possible lens diameter you would need in order to resolve these two stars?

A monochromatic beam of light in air has a wavelength of 589 nm in air. it passes through Carbon disulfate (n=1.63) and then through glass (=1.52). what is its wavelength in glass? Group of answer choices 421 nm 388 nm 487 nm 361 nm

A light ray strikes a 10-cm-thick glass pane, making a 30° angle to the perpendicular to the glass as it enters.  When the ray reemerges into air on the other side of the pane, how much has it been displaced from where it would have been if the glass weren't there (this is the distance d indicated in the figure below)? A 1.25 cm B 2.23 cm C 1.94 cm D 2.46 cm

1. A flashlight held 1.3 m above the surface of a water tank shines a beam of light on the water (index of refraction n 1.33). The light hits the water 2.7 m away from the edge of the tank, where the flashlight is held. The water tank is 2.1 m deep. (a) What is the incident angle relative to the normal? (b) What is the transmitted angle relative to the normal? (c) Where does the light ray hit the bottom of the water tank, mea- sured from the edge of the tank where the flashlight is held? light ray 2.7 m d=? = water tank 1.3 m 2.1 m

Q1: If the refractive indexes of the mica plate in the direction of the slow axis and the fast axis are as follows: n =1.5977, n1= 1.5936, Find the thickness of this plate needed to make the optical path difference between the two rays passing through the plate equal to a quarter of the wavelength if light of its wavelength was passed through A = 5890 nm.
