Problem 1.6 determine an expression for an exponentially decaying sinusoid that oscillates three times per second and whose amplitude decreases by 50% every 2 seconds. use matlab to plot the signal over-2 a) t 2 b) when a bel is struck with a mallet, t produces a ringing sound. write an equation that approximates the sound produced by a small i. e., light) bell. your equation should include the amplitude of the sound wave. does amplitude remain constant over time? justify your answer. in addition, you should be able to hear the sound from this bell: sound is a wave in 20 hz - 20 khz frequency range c) you probably know that smaller bell will produce higher frequency sound compared to the larger and heavier bell. also, larger/heavier bell will produce a louder sound (i. e., higher amplitude). now let write an equation for the larger/heavier bell

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?
