As shown in the figure, the angle between two plane mirrors (M, and M,) is 125°. If the incident ray strikes mirror M, with an angle of incidence 0, = 67°, determine the angle of reflection 0,, for mirror M,. M2 ,02 125° M1

An underwater scuba diver sees the Sun at an apparent angle of 31.0° from the vertical. What is actual direction of the Sun? ° (above the horizon)

Spherical refracting surfaces. An object O stands on the central axis of a spherical refracting surface. For this situation (see the table below, all distances are in centimeters), nį is the index of refraction where the object is located, n2 is the index of refraction on the other side of the refracting surface. Find (a) the image distance i, and determine whether the image is (b) real or virtual and (c) on the same side of the surface as object O or on the opposite side.

Let IB and OB be distances from the plane mirror to the image and object, respectively. Show that IB = OB. Prove that image and object have the same size.

More mirrors. Object O stands on the central axis of a spherical or plane mirror. For this situation (see the table below, all distances are in centimeters), find (a) the type of mirror, (b) the radius of curvaturer (nonzero number or O if infinity), (c) the object distance p, (d) the image distance i, whether (e) the image is real or virtual, (f) inverted or noninverted from O, and (g) on the same side of the mirror as object O or on the opposite side.

A very large piece of clear ice has a cave man frozen inside it. When viewed at an anglefrom the top of the ice the cave man appears to be 1.00 ft below the surface of the ice.What is the actual depth (in units of inches) of the cave man from the top of the ice?The index of refraction of the ice is 1.309   Do NOT use i for the angle of incidence or r for the refracted angle

I ONLY NEED HELP WITH PART A AND D

More mirrors. Object O stands on the central axis of a spherical or plane mirror. For this situation (see the table below, all distances are in centimeters), find (a) the type of mirror, (b) the focal length of the mirror (including sign), (c) the radius of curvaturer (nonzero number or O if infinity), (d) the image distance i, whether (e) the image is real or virtual, (f) inverted or noninverted from O, and (g) on the same side of the mirror as object O or on the opposite side.

As shown in the figure, a light beam travels from air, through olive oil, and then into water. If the angle of refraction 82 for the light in the olive oil is 34.8°, determine the angle of incidence e, in air and the angle of refraction e3 in water. The index of refraction for olive oil is 1.47. 83 = air oil water
