Hi! This is my mixed semester review for Physics. Can you pls help me understand and answer these 5 questions. Answers should be rounded to the hundredths place. Thank you!!! :)

22.There is a column of air resonating In a tube. The tube is open on both ends. The vibration has a frequency of 447 Hz. The vibration is known to be the 6th harmonic. The speed of sound is 343 m/s. How long is the tube? 23. Joey is standing on a dock that is 7 meters wide. He notices that it takes 1 seconds for a wave to travel the width of the dock. He then stands on one edge of the dock and counts the number of waves that pass. He measures 5 waves pass in 16 seconds. Calculate the wavelength. 24. There is a 3 meter string that is fixed at both ends and is vibrated at a rate of 453 Hz. The resulting is shown below: Calculate the frequency of the 16th harmonic 25. A ray of light is pointed at the collection of mirrors. The result is pictured below. Given that 0, is 55 degrees and 0, is 119 degrees, calculate B. 82 26. A 1.6 meter tall snowman is located 20 meters in front of a converging lens. The image created is 9.5 meters tall. Calculate the distance from the lens to the image created
