2) What determines the "loudness" of a musical note? A) velocity B) wavelength C) phase D)...
Two different musical instruments, a trombone and a bassoon, play notes of equal loudness with the same fundamental frequency. The two sounds differ primarily in: a pitch. b intensity level. c amplitude. d timbre. e wavelength.
1. Which of these relate most to the loudness of sound? Select one: a. wavelength. b. frequency. c. speed. d. amplitude. e. all of the above 2. The principle of continuity states that for fluid flow to be continuous it must Select one: a. speed up in narrow regions of flow. b. slow down in wide regions of flow. c. both of these d. neither of these 3. Both a transverse wave and a longitudinal wave have Select one: a....
1. To measure the phase velocity in a medium, especially if it is not vacuum, is rather difficult. Instead, it is proposed to proceed as follows: 1. Generate an electric field intensity in the medium with permeability μ and permittivity ε at some arbitrary frequency assuming that this is a plane wave. Assume a lossless medium. Measure the amplitude of the electric field intensity E. 2. Measure the amplitude of the magnetic flux density B, produced by the electric field...
Middle-C on a piano (C4) is a musical note that has a frequency of 261.626 Hz. What is the frequency of the note three octaves above middle-C (C7)?
a multiple of the logarithm of the ratio of those two quantities. Une instance was the decibel as a measure of the loudness of sound. The other was the seismic moment magnitude scale as a measure of the intensity of earthquakes. Here is a third one. This one measures how different are the frequencies of two musical tones. The relevant unit is called a cent. If one knows the frequencies fi and f2 musical interval from fi to fo is...

24 pts. Phase and group velocity of a plasma. The permittivity ε of a plasma (ionized gas) is a function of frequency given by: I. Eo where co is radian frequency and o the "plasma frequency", which is assumed to be a constant related to the properties of the ionized gas. (a) 6 pts. Given the relation above, write an expression for the phase velocity in a plasma. (Assume μ-,-1). (b) 2 pts. Write an expression for the magnitude of...
1. Two waves of the same wavelength interfere - in which case(s) below, will the two waves experience fully destructive interference? (Note: π is "pi") A) the two waves are 90o degrees apart in phase B) the two waves are 2π radians apart in phase C) the two waves are π radians apart in phase D) the two waves are 1.5 wavelengths apart in phase E) the two waves are one wavelength apart in phase F) the two waves are...
