A344-nm thick film coats a glass surface. the indices of refraction of the film and the glass are 1.4 and 1.50, respectively. the surface of the film is illuminated from above at normal incidence with white light.

a) what are the two wavelengths of light in the 400 nm to 800 nm wavelength band that are most strongly reflected? express your answer in nm.

b) what is the wavelength of light in the 400 nm to 800 nm wavelength band that is most weakly reflected? the wavelength of light in the 400 nm to 800 nm wavelength band that is most weakly reflected, in nm.

the wavelength will be 2 to and yes it is the most waekly reflected. so of course the wavelength of li8 400nm to 800nm hope this will help you

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

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.
