2nd Semester Final Flashcards
Give an example of a transverse wave and describe the different parts of the wave
ripples on water, parts of wave Amplitude, Wavelength, Frequency, crest, trough
Give an example of a compressional wave and describe the parts of the wave.
Sound wave, the parts are, compressions, rarefactions, Frequency, and wavelength
The sun shines through a light rain creating a rainbow. What property of light waves is being demonstrated.
It is the property of reflection because the light goes through the water then the light comes out of the water droplets and it comes out in all the colors of the rainbow
Explain how the wavelength and frequency of a wave are related to the amount of energy in a wave.
The shorter the wave length the higher the frequency the higher the energy in the wave
You are standing in a large empty building and as you talk you can hear your voice return to you after a second or two. What property of waves is being demonstrated. Explain your answer.
Sound waves, when you talk your voice hits a wall and reflects all around it will hit one wall then hit another and it will come back to you after 2 seconds.
What property of the sun controls the orbits of the planets?
Gravity, becAuse there is no other source in our solar system that can pull them out of that gravitational pull from the sun
