How does the energy carried by sound waves compare to the energy carried by light waves (in the same amount of time)?
In which of the following ways are sound waves different from light waves? Select the correct answer Sound waves must propagate through some medium, while light waves can propagate in a vacuum Audible sound waves have much lower frequencies than visible light waves Sound waves are longitudinal while light wavesY are transverse Your Answe O All of the listed options are valid. Audible sound waves have much longer wavelengths than visible light waves
Which of the following is NOT true for electromagnetic waves? (a) they transport energy (b) they transport momentum (c) they consist of changing electric and magnetic fields (d) they travel at different speeds in vacuum, depending on their frequency e) they can be reflected We perceive frequency for sound wave as pitch. What do we perceive frequency for light waves? (a) Color (b) Brightness (c) opacity (d) Shininess Unpolarized light passes through a single polarizer with an intensity of 10.00...
Which of the following is not an example of a transverse Wave? The wave in a football stadium A water wave in a wave pool Sound A plucked guitar string 2) Why do people count the time between a lightning strike and when the thunder is heard? The longer the thunder takes to be heard the more severe the storm You can approximate the distance the storm is away from you because sound travels much slower than light They have nothing...
A light wave is like a sound wave in that both are longitudinal waves. are means of transmitting energy are transverse waves require a material medium for propagation. have the same velocity in air A 60° prism has a refractive index of 1.64 for blue light and 1.61 for red light. Calculate the difference in the angle of emergence from the opposite face of the prism for a beam of red light and a beam of blue light that are...
4. A wave of light a-638 am) enters a block of material. The wavelength of light within the material is 510 nm. What is the index of refraction of the material? (A) 0.5 (B) 0.8 (C) 1.2 (D) 1.25 5. A jackhammer operator wears a set of protective headphones. Through the headphones, a sound wave is broadcast that is 180° out of phase with the jackhammer sound wave. The result is that he does not hear the sound of the...
Which of the following is NOT a property of sound waves? A. The speed of sound waves in air depends on the temperature of the air B. The pitch of a sound wave is closely related to its frequency C. The loudness of a sound wave is related to its amplitude and frequency D. Sound waves can travel through empty space
QUESTION 1 Which of the following types of wave pulses gets inverted ("flipped") at a boundary between two different wave media? A. The transmitted wave, if the second medium is more dense OB. The transmitted wave if the second medium is less dense C. The reflected wave if the second medium is less dense D. The reflected wave if the second medium is more dense QUESTION 2 What is the wavelength of a standing wave on a string of length...
