How would you design an experiment to observe barrier penetration with sound waves? What range of thicknesses would you choose for the barrier? I believe this needs to be a diagram.

How would you design an experiment to observe barrier penetration with sound waves? What range of thicknesses would you choose for the barrier?
3. a) In an experiment with sound waves in a tube, one group of students found resonant frequencies at 540 Hz, 720 Hz, and 900 Hz. What is likely the fundamental frequency of this series? List at least one other resonant frequency they should be able to find. b) Another group of students is also experimenting with sound waves in the same length tube and finds resonance at 270 Hz, 450 Hz, and 630 Hz. One student in the group...
PHET Sound Simulation Purpose - To explore sound (a longitudinal wave) and how it can be modeled as a transverse wave Obtain com puter with PHET software on it. Get headphones if possible and plug into sound port. Open PHET simulations and find Sound and Waves simulations. Open the simulation called "Sound". There are 5 tabs. Listen to a Measure Two Source Interference Listen with Interference by Reflection Varying Air Pressure Single Source Open the one called listen to a...
(5) (a) Describe how you would design a manipulative experiment to demonstrate that longer manes in lions are selected for by female choice. (b) What would be the null hypothesis? (6) Two species of insects (the Kamarla beetle and the Chelsea beetle) are both bright orange in color and are both unpalatable to birds. Describe an experimental design to test whether or not they are mutualists.
1) How would you describe thunder and the light from lightening as waves? -A) Thunder longitudinal, lightening transverse -B) Thunder transverse, lightening transverse -C) Thunder transverse, lightening longitudinal -D) Thunder longitudinal, lightening longitudinal 2) Suppose the longitudinal component of a wave created by an earthquake is travelling from east to west. As it passes through your position, how would you expect to move? -A) Both up and down, and north and south -B) east and west -C) north and south...
In your opinion, what barrier to communication is the most detrimental? How would you remove it?
Researchers followed tagged blue whales to observe how they respond to simulated military sonar-using sound levels much lower than those typically used during military exercises. The researchers also measured the speed and direction of whale swimming in response to the sound exposure. Whales increase their speed and swim away from the direction of sound. Design a study to test the hypothesis that this behaviour leads to beach strandings. Note that you will not receive permission to conduct the study if...
If you were going to design an experiment on the effects of air pollution, how would you account for the effects that variations in health, gender, age, and ethnicity can cause? If you were going to measure whether two groups differ in a genetic predisposition to heart disease, stroke, or hypertension, how would you make sure that difference in air pollution levels experienced by the two groups didn't confound your results?
Design an experiment that would test the effect of removing heat energy from a slightly stretched rubber band. You will not perform this experiment, but the materials you intend to use should be ones you would normally find at a college. Include in your design: A list of the materials required. A brief description of the procedure you would use (a diagram might be useful). The observations you would expect to see. Explain these observations in terms of both free...
How would you design an experiment to test whether a tranduction event occured between two different bacterial strains?
Please help with question 2,3
and 4 and filling out the table
Lab 12. Sound Waves and Beats Introduction Sound waves consist of a series of air pressure variations. A Microphone diaphragm records these variations by moving in response to the pressure changes. The diaphragm motion is then converted to an electrical signal. Using a Microphone and an interface, you can explore the properties of common sounds. The first property you will measure is the period, or the time for...
