Gg 1. Assume that pupillary distance between your two eyes is 63 mm. Write a calculator that determines the object distance based on the angle that an external point object distends between the pupils. Give the angle for objects at 30 cm, 1 m, and 10 m. Give your answers in degrees correct to 3 significant digits.

The basic concepts of "line" and "point" can be used to define a ray. A ray is a portion of a line that starts at a point and extends in a particular direction. How can this definition of a ray be used to formulate a definition of an angle? O An angle is the intersection of two rays at a common point. O An angle is a special kind of ray that points in two particular directions. An angle is the figure formed by two rays that lie on the same line. An angle is a figure formed by two rays extending from a common point.
A ray of light is passed through a ruby and it hits a surface in contact with air (n = 1.000) at an angle of 45° with respect to the normal. Use the table below to determine happens when it hits the surface? What is the critical angle? The ray refracts into the air at an angle of 45° with respect to the normal. The ray reflects back into the ruby at an angle of 45° with respect to the normal. The ray refracts at an angle of 90° with respect to the normal, along the surface. The ray is absorbed in the air. None of the above.

A 45°-90°-45° prism is constructed from a synthetic resin. As shown in the figure, a light beam that enters the prism at the midpoint of the long side and parallel to the base exits the prism at an angle of 28° below the horizontal. What is the index of refraction of this prism? 1.39 Have you drawn a figure showing all angles and established any relationships between the angles? Have you written a Snell's law statement for the light as it enters and exits the prism? Depending on how you solve the problem, you may need the identities tan a = sin a / cos a and sin(a + 6) = sin a cos pi cos a sin ß. Additional Materials Reading
Estimate the height of the building shown in the following figure by the method of triangulation. The person is standing 5 meters from a pole, which is 15 meters from the building. The person's vision perceives the top of the pole aligned with the top of the building. The person is approximately 1.75 meters and the pole is approximately 3.5 meters. 15 m b) Estimate the volume and mass of water that exists in a lake. The shape of the lake is approximately circular, it is almost 500 meters in diameter and is supposed to have a average depth of 20.0 meters. Remember that the density of water is equal to 1000 Kg / m3 d= 500m h = 20.0m
