Find the magnification of the heater element, given that the mirror has a radius of curvature of 51 cm and produces an image of the coils 2.8 m away from the mirror.

A laser beam is incident at an angle of 30.2° to the vertical onto a solution of corn syrup in water. (a) If the beam is refracted to 19.20° to the vertical, what is the index of refraction of the syrup solution? (b) Suppose the light is red, with wavelength 632.8 nm in a vacuum. Find its wavelength in the solution. nm (c) Find its frequency in the solution. Hz (d) Find its speed in the solution. m/s

A glass optical fiber is used to transport a light ray across a long distance. The fiber has an index of refraction of 1.520 and is submerged in ethyl alcohol, which has an index of refraction of 1.361. What is the critical angle (in degrees) for the light ray to remain inside the fiber?

To the nearest hundredth of an hour, how many hours are required before a radio signal from a space probe near the planet Uranus reaches Earth, 1.607 *109 km away? A light ray is reflected from a mirror with an angle 15.2° to the normal. What was the angle of incidence? Light passes through a transparent substance at a speed of 2.256 ×108 m/s.

A student stands dsub0=2.4 m in front of a floor-to-ceiling mirror. Her eyes are hsube=1.53 m above the floor and she holds a flashlight at a distance hsubf=.55 m above the floor. Calculate the angle in degrees that the flashlight makes with respect to the floor if the light is reflected into her eyes.
