What magnifying power is attained using a compound microscope with the following specifications: obiectiye focal length 0.60 cm, eyepiece focal length 3.60 cm, tube length 15.0 cm? Assume a near point of 25.0 cm. Enter the numerical part of your answer to the nearest integer. Your Answer: :] Answer Prof. Lam is a nearsighted person, who has a far point of 25.0 cm. Calculate the refractive power (in D) needed for their contact lenses. Enter the numerical part of your answer to two decimal figures. Hint: Remember that the sign of the refractive power is important. Your Answer:A light rayr in a particular medium hits the surface with air {n1 = nair = 1.00} at an angle of incidence cut 5?.5\". The angle of refraction in air is 28.9\". Calculate the refractive index n2 for this medium. Enter the numerical part at your answer '[0 two decimal figures. The speed of light in a vacuum = c = 3.00 x 108 mils. Question 38 (1 point) The diagram shows a light ray passing through a medium with refractive index nz into a second medium with a larger refractive index my, where my > n2. The angle of incidence is incidence = 45. 11 12 1 10 2 45" 9 3 n1 n2 4 7 6 5 Using the clock face, indicate the approximate direction of the refracted light ray in the second medium. Hint: For example, a refracted light ray that is in a horizontally left-ward direction (8 = 0") would be indicated by "9 o'clock". (And so on)
