Athin layer of turpentine (n=1.472) is floating on water (n=1.333). light of wavelength 589 nm initially traveling in air is incident on the turpentine at an angle of 24.8° measured with respect to the air-turpentine interface. what is the light's refraction angle in the turpentine?

16.6 degrees

Explanation:

We can solve the problem by using Snell's law for refraction:

where:

is the index of refraction of the first medium (air)

is the angle of incidence

is the index of refraction of the second medium (turpentine)

is the angle of refraction of light in turpentine

By re-arranging the equation and using the numbers, we find

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
