A silver coin sits on the bottom of a swimming pool that is 4 meters deep. A beam of light reflected from the coin emerges from the pool making an angle of 20 degrees with respect to the water’s surface and enters the eye of an observer. Extend this ray, which goes from the water-air surface to the eye, straight back until it intersects with the vertical line drawn through the coin. What is the apparent depth of the swimming...

A thin hemispherical bowl of clear plastic floats on water in a tank. The radius of the bowl is 50 cm and the depth of the bowl in water is 10 cm. The depth of the water (n = 1.33) in the tank is h = 590 cm. An object 8.0 cm long is on the bottom of the tank directly below the bowl. The object is viewed from directly above the bowl. Ignore the refractive effects of the plastic....

A swimming pool appears to be 3.30 m deep when looking at an angle of incidence of 25 degrees, how deep is it really? n = 1.33   My professor provided this as the answer: "Use the approximation that the x distance doesn't appear to change, just the y depth. This isn't completely true, but is a good approximation. That means our eyes believe the light doesn't bend. So we think the triangle below the surface still is at an angle...

1) Two convex lenses, both with focal length 1.5 m, are placed such that the light from a 4 cm tall object passes through each. The object is placed 4.5 m from the first lens, and the lenses are 3 m apart. Where will the image from the first lens be? Will it be real or virtual? Will it be upright or inverted? Where will the final image be (using both lenses)? Will it be real or virtual? Upright or...

1- An object of 5 cm in height is 40 cm from a converging lens. It produces an inverted image which is found 30 cm from the lens. Find a) the focal length of the lens, b) the magnification, and c) the image height. 2-A laser of 632.8 nm (red) is incident on a rectangular glass container filled with water. Assume the glass is thin enough that we ignore the refraction it causes and only focus on the water. If...
