a-d) Sound standing waves are formed inside a 0.8 m long tube closed at one end, like the one shown below. Draw the standing wave pattern for the first four harmonics. For each case complete the equation showing the relationship between the length of the tube and the wavelength. NOTE: Reproduce the table below on paper, draw and fill in the information required, then scan as pdf and submit. Harmonic # Standing Wave Pattern | Length as a function of A 1 L= 2 L= 3 L =______X 4 L= e) If the speed of sound is 342 m/s what is the frequency of the second harmonic?

A light ray is incident on the surface of a material (n=2.3) at an angle of 20 deg. relative to the normal to the surface. Calculate the angle of the reflected ray.

A light ray is incident on the surface of water (n=1.33) at an angle of 60 degree relative to the normal to the surface. Calculate the angle of the refracted ray.

A jeweler places a new gem in a glass container filled with a solvent (index of refraction 1.56) in order to clean it. The gem appears to vanish. What is its index of refraction? 1.5600 You are correct. Computer's answer now shown above. Previous Tries Your receipt no. is 155-101 ? In air, a laser is shined on the gem with an incident angle of 30 degrees. What is the angle (in deg) of the refracted light inside the gem? 18.6939 deg You are correct. Computer's answer now shown above. Your receipt no. is 155-1615 ? Previous Tries The laser light is transmitted through the gem and exits from a facet which is parallel to the surface where the light enters. What is the angle (relative to the surface normal) of the light which emerges from the gem? Submit Answer Tries 0/10
