Calculating with Faraday's 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.
Index of Refraction
6.1 Frequency
Light having a frequency in vacuum of 5.4 x 10^11 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 700 nm enters a liquid of refractive index 2.0. In this liquid, its wavelength will be.
