<p> Science Questions of the Day</p><p>Waves-Week 2</p><p>Answers:</p><p>1) Does water moving through a hose qualify as a wave? Explain why or why not. Answer: No, the water travels from one end of the hose, to the other. In a wave, the disturbance moves, but the medium does not.</p><p>2) When you make sounds by plucking a rubber band, you make the rubber band move back and forth quickly. What is this called? </p><p>Answer: Vibration</p><p>3) The distance between two crests or troughs is called? </p><p>Answer: Wavelength</p><p>4) What is the lowest part of a wave? </p><p>Answer: Trough</p><p>5) Suppose you drop a cookie crumb in your milk, you see ripples spreading across the surface of the milk. What types of waves are these and what is the disturbance? Answer: Transverse Waves and the falling crumb.</p><p>6) For wave refraction to take place, a new medium must enter a new medium.</p><p>7) What is the highest point of a wave? Answer: Crest</p><p>8) The direction in which a transverse wave travels is ______. </p><p>Answer: At right angles to the disturbance. </p><p>9) As you increase energy transferred increases the ______. </p><p>Answer: Amplitude.</p><p>10)Which statement best describes the relationship between frequency and wavelength? </p><p>Answer: When frequency increases, wavelength decreases.</p><p>11)Which setup in a wave tank would enable you to demonstrate diffraction? </p><p>Answer: Water and a Barrier with a Small Gap.</p><p>12)Two waves come together and interact to form a new, smaller wave. This process is called destructive inference.</p><p>13)Explain how a wave can travel through a medium and yet the medium stays in place. Use the term energy in your answer. Answer: Energy travels through a medium, leaving the matter in place.</p><p>14)Describe two ways in which the waves travel, and give an example of each. </p><p>Answer: Transverse waves travel at right angles to the disturbance. Longitudinal waves travel in the same direction as the disturbance. Examples: Ocean waves, and sound waves. 15)To identify the amplitude in a longitudinal wave, you would look for areas of ______. </p><p>Answer: Compression.</p>
