For each unexcused absence that exceeds the four “grace” sessions of 55-minutes, 5% will be deducted from my final course grade at the end of the semester.

8.     Texas is the only mainland state with its power grid, heralded until recently for producing more electricity than any other.  _______

in the absence of sufficient US troops to confront the Soviet army in Eastern Europe, what defense strategy was developed by the late 1940s?

Under the National Recovery Administration, industry was encouraged to adopt “codes of fair practice” that would do all of the following EXCEPT…

The schematic illustrates the far point and near point of the eye. Given that q = cm, p = 10 cm, and d = 1.7 cm, determine the refractive power (in diopters) of a corrective lens required so that the person can see objects at a distance of 65 cm clearly with the eye relaxed.  

A lens with f = + cm is in contact with a lens with f = -20 cm. What is the focal length of the combination (unit in cm)?

The schematic illustrates the far point and near point of the eye. Given that q = 80 cm, p = cm, and d = 1.7 cm, determine the power of accommodation of the eye (in diopters).

The schematic illustrates the far point and near point of the eye. Given that q = cm, p = 25 cm, and d = 1.7 cm, determine the refractive power (in diopters) of a corrective lens required so that objects at infinite distance can be seen clearly.

You combine two thin lenses by placing them in contact so that their axes coincide, forming what is called a compound lens. The focal lengths of the lenses are 30 cm and −50 cm, respectively. If an object is cm tall and d1 = cm, what is the height of the image (unit in cm)? Express the answer as a positive quantity.

A light beam strikes a piece of glass with an incident angle of 45o. The beam contains two colors:  450 nm and an unknown wavelength. The index of refraction for the 450-nm light is . Assume the glass is surrounded by air, which has an index of refraction of 1. Determine the index of refraction nu for the unknown wavelength if its refraction angle is o greater than that of the 450 nm light.
