You have enrolled in a scuba diving class and while swimming under water in a nearby lake you look up and note that the Sun appears to be at an angle of 28° from the vertical. At what angle above the horizon does the diving instructor standing on shore see the Sun?

The answer isn’t c.

You have enrolled in a scuba diving class and while swimming under water in a nearby lake you look up and note that the Sun appears to be at an angle of 17° from the vertical. At what angle above the horizon does the diving instructor standing on shore see the Sun? °

An underwater scuba diver sees the Sun at an apparent angle of 44.0° above the horizontal. What is the actual elevation angle of the Sun above the horizontal? (Use 1.333 for the index of refraction of water.)

Calculate the critical angle for zircon when surrounded by air. Assume that lambda = 582 nm.

An orthogonal projection of an object in a 2D drawing of an object as it would appear with all its feature projected perpendicular to a viewing ...True? A. yes    B.No

Help please

A critical angle exists when a light ray travels O through a single medium O from a medium with a low index of refraction to a medium with a high index of refraction O from a medium with a high index of refraction to a medium with a low index of refraction O perpendicular to the boundary between media

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 49.0 km due east and have it detected by a light sensor that is 117 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west. (b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.003°. Determine how far south you need to move the light sensor in order to detect the reflected laser light.
