Question

3. The critical angle for total internal reflection at a liquid-air interface is 48.6'. If a ray of light travelling in the liquid has an angle of incidence at the interface of 40.0º, what angle does the refracted ray in the air make with the normal? If a ray of light traveling in air has an angle of incidence at the interface of 40.0', what angle does the refracted ray in the liquid make with the normal? The focal length of the eyepiece of a certain microscope is 20.0 mm. The focal length of the objective is 10.0 mm. The distance between objective and eyepiece is 25.0 cm. The final image formed by the eyepiece is at infinity. Treat all lenses as thin. What is the distance from the objective to the object being viewed? What is the magnitude of the linear magnification produced by the objective? What is the overall angular magnification of the microscope? 6. What is the wavelength of light falling on double slits separated by 2.06 um, if the third-order minimum is at an angle of 60.00?
