Question
Answered step-by-step
(II) A sound wave is traveling in warm air $\left(25^{\circ} \mathrm{C}\right)$ when it hits a layer of cold $\left(-15^{\circ} \mathrm{C}\right)$ denser air. If the sound wave hits the cold air interface at an angle of $33^{\circ}$ , what is the angle of refraction? The speed of sound as a function of temperature can be approximated by $v=(331+0.60 T) \mathrm{m} / \mathrm{s},$ where $T$ is in $^{\circ} \mathrm{C} .$

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays. Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

In physics, Maxwell's equations are a set of partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. They underpin all electric, optical and radio such electromagnetic technologies as power generation, electric motors, wireless communication, cameras, televisions, computers, and radar. Maxwell's equations describe how electric and magnetic fields are generated by charges, currents, and changes of these fields. The equations have two major variants. The microscopic Maxwell equations have universal applicability but are unwieldy for common calculations. They relate the electric and magnetic fields to total charge and total current, including the complicated charges and currents in materials at the atomic scale. The macroscopic Maxwell equations define two new auxiliary fields that describe the large-scale behaviour of matter without having to consider atomic scale details. The equations were published by Maxwell in his 1864 paper "A Dynamical Theory of the Electromagnetic Field". In the original paper Maxwell fully derived them from the Lorentz force law (without using the Lorentz transformation) and also from the conservation of energy and momentum.

here in this problem, we have given dispute off there as a function off temperature is 331 Bless 0.60 in two d. This is the its speed function as a function off T. Now we have to find the angle. We know that Sign off, Tita, to develop. I sign off. Heat oven should be equal toe we to buy even. We have reduced the speed in William too. And women is their speed. And William one. So we can write we to 3 31 plus zero find 60 the temperature here minus 15. No, for we even we will ride 3 31 plus 0.60 into Stephen which is 25 C. From here we can write sign off hitter too. Will the equal toe sign Peter one indoor? We can write it 3. 22 D world by 3. 46. No theater one is here giving. We just signed 33 in tow. 3. 22 divided by 3. 46. So we can bite, Peter. Two will be equal toe sine inverse 0.5069 After calculating this, we will get the value of theater too. It is around active, agree And this is where answer
