Consider a double-slit with a distance between the slits of 0.04 mm and slit width of 0.01 mm. suppose the screen is a distance of 1 m from the double-slit and light with a wavelength of 600 nm is illuminating the slits. what is the distance δxa between the places where the intensity is zero due to the single slit effect? give answer in mm to two significant figures. what is the distance δxd in mm between the places where the intensity is zero due to the double slit effect?

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.

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.
