Please solve the following questions given below. You must show all work for full/partial credit. Question 1) An antenna is connected to a car battery. Will the antenna emit electromagnetic radiation? Why or why not? Explain. Only consider steady state, that is after the connection is made and not during initial or final disconnection. Question 2) A light-year is a measure of distance (not time). How many meters does light travel in a year? Question 3) How long does it take a laser beam to travel to the Moon and back? Take the Earth Moon distance to 384,000 km.
Question 4) A beam of light is incident on a plane mirror at an angle of 35o. If the mirror rotates through a small angle through what angle will the reflected ray rotate? Question 5) The speed of light in polythene is 1.99 x 108 m/s What is the index of refraction of polythene? Question 6) A beam of light with red and blue components of wavelengths 670 nm and 425 nm, respectively, strikes a slab of fused quartz at an incident angle of 30o. On refraction, the different components are separated by an angle of 0.001312 rad. If the index of refractions of the red light is 1.4925, what is the index of refraction of the blue light? HINT: Be sure you convert radians to degrees to use Snell's Law.
The outer edge of a rotating Frisbee with a diameter of 29cm hasa linear speed of 3.7m/s. What is the angular speed of the Frisbee?
What is the magnitude of the free-fall acceleration of a ball (mass m) due to the Earth's gravity at an altitude of 3R, where R is the radius of the Earth
A positively-charged object with a mass of 0.177 kg oscillates atthe end of a spring, generating ELF (extremely low frequency) radiowaves that have a wavelength of 5.86 x 107 m. Thefrequency of these radio waves is the same as the frequency atwhic..
