When light propagates from a material with a given index of refraction into a material with a smaller index of refraction, the speed of light
What is the minimum value that the index of refraction can have?
etc …
Part A = 10 dB
Part B = 20 dB
Part C = 3,6,9 dB
What is the sound intensity level Β, in decibels, of a sound wave whose intensity is 10 times the reference intensity (i.e., I = 10I0)?
What is the sound intensity level Β, in decibels, of a sound wave whose intensity is 100 times the reference intensity (i.e., I = 100I0)?
Calculate the change in decibels (ΔΒ2, ΔΒ4, and ΔΒ8) corresponding to f = 2, f = 4, and f = 8.
Part A = 2.26 m/s
Part B = 3.28 m/s
A bucket of mass 1.80 kg is whirled in a vertical circle of radius 1.10 m. At the lowest point of its motion the tension in the rope supporting the bucket is 26.0 N.
Find the speed of the bucket.
How fast must the bucket move at the top of the circle so that the rope does not go slack?
Part A = 31.8 cm
Part B = 23.6 cm
Part C = Upright
Part D = 19.42 cm
Part E = The image is a different size and oriented differently.
A compound lens system consists of two converging lenses, one at x = -20.0 cm with focal length f1 = +10.0 cm, and the other at x = +20.0 cm with focal length f2 = +8.0 cm . An object 1.00 centimeter tall is placed at x = -50.0 cm.
What is the location of the final image produced by the compound lens system? Give the x coordinate of the image.

Two identical pulses are moving in opposite directions along a stretched string that has one fixed end and the other movable, as shown in the figure. Initially, the pulses are moving away from each other.
Which sequence correctly represents the displacement of the string as the pulses interfere?
