Sunlight is composed of wavelengths of light that make up part of the electromagnetic spectrum. Towson University Exam Question. The frequency of a wave is directly proportional to the speed at which the wave is traveling. Do NOT Copy! Calculate the frequency (in Hz) of light at the following wavelength:

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
