Find the true statement. use the underlined word to determine whether the statement is true or false. question 3 options: electromagnetic waves are mechanical because they require a medium to travel. electromagnetic waves are transverse because they have electric and magnetic fields that move perpendicular to the direction of energy transfer. the speed of an electromagnetic wave depends on the frequency of the wave. gamma rays are faster than radio waves. as the frequency of an em wave increases, so does the wavelength. they are directly related.

Road users moving into your lane, brake lights, and abrupt changes in road surface are a. rare at night b. indicators of potential hazards c. not worth worrying about before you reach them d. no problem for experienced drivers

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.

The diagram shows a wave. the quantity shown is the amplitude. this quantity is directly proportional to which of these other quantities? a) energy b) frequency c) period d) wavelength
