5 Calculating with Faradays law and magnetic flux
A flat circular coil of wire has a radius of 0.18 m and is made of 75 turns of wire. The coil is lying flat on a
level surface, and is entirely within a uniform magnetic field with a magnitude of 0.55 T, pointing
straight into the paper. The magnetic field is then completely removed over a time duration of 0.050 s.
Calculate the average magnitude of the induced EMF during this time
duration.
6 Index of Refraction
6.1 Frequency
Light having a frequency in vacuum of 5.4 x $10^{14}$ Hz enters a liquid of refractive index 2.0.
In this liquid, its frequency will be:
6.2 Wavelength
Light having a wavelength in vacuum of 700nm enters a liquid of refractive index 2.0.
In this liquid, its wavelength will be:
