•1 In Fig. 35-31, a light wave along ray r, reflects once from a mirror and a light wave along ray r, reflects twice from that same mirror and once from a tiny mirror at distance L from the bigger mirror. (Neglect the slight tilt Figure 35-31 Problems 1 and 2. of the rays.) The waves have wave- length 620 nm and are initially in phase. (a) What is the smallest value of L that puts the final light waves exactly out of phase? (b) With the tiny mirror initially at that value of L, how far must it be moved away from the bigger mirror to again put the final waves out of phase?

33.37 • BIO Heart Sonogram. Physicians use high-frequency (f = 1–5 MHz) sound waves, called ultrasound, to image internal or- gans. The speed of these ultrasound waves is 1480 m/s in muscle and 344 m/s in air. We define the index of refraction of a material for sound waves to be the ratio of the speed of sound in air to the speed of sound in the material. Snell's law then applies to the refraction of sound waves. (a) At what angle from the normal does an ultrasound beam enter the heart if it leaves the lungs at an angle of 9.73° from the normal to the heart wall? (Assume that the speed of sound in the lungs is 344 m/s.) (b) What is the critical angle for sound waves in air incident on muscle?
(c) In an experiment, two light waves having wavelength of 501 nm each with equal amplitudes and equal phase enter media 1 (air) and 2 (transparent plastic layer). The medium 2 has a refractive index of 1.6. The thickness of both the media is 2.01 μm. (i) Determine the phase difference of the emerging waves coming out of the media in wavelengths, radians, and degrees? (ii) What is their effective phase difference (in wavelengths)?

Chapter 25: Problem 5: In the year 1178, five monks at Canterbury Cathedral in England observed what appeared to be an asteroid colliding with the moon, causing a red glow in and around it. It is hypothesized that this event created the crater Giordano Bruno, which is right on the edge of the area we can usually see from Earth. a) How long after the asteroid hit the Moon, which is 3.84 ×10⁵ km away, would the light first arrive on Earth in seconds?
