Two strings are tied together and a wave is sent down string 1. String 1 has a linear mass density three times smaller than string 2. When the wave reaches the point where the strings are tied together and moves through string 2, you observe the wavelength. Is the wavelength in string 2 greater than, less than, or equal to the wavelength in string 1?
Muscovite, which as \(n = 1.56\text{,}\) or better known as mica, is a phyllosilicate mineral of aluminum and potassium. New industrial uses include being an insulator, usually for small electrical components. Fabrication of devices with mica often require high precision in the determination of the mica thickness. If a mica sheet is suspended in air and reflected light shows gaps in the visible spectrum at \(450\text{,}\)\(525\text{,}\) and \(630 \mathrm{~nm}\text{,}\) what is the thickness of the mica sheet?
A cylindrical tube of air sustains standing waves at \(600 \mathrm{~Hz}\text{,}\)\(800 \mathrm{~Hz}\text{,}\) and \(1000 \mathrm{~Hz}\text{,}\) but at no other frequencies between \(600\) and \(1000 \mathrm{~Hz}\text{.}\) Which of the following statements are plausible here?
Suppose you observe that the shortest non-zero path length difference that produces constructive interference from two coherent unknown sources is \(128 \mathrm{~m}\text{.}\) What is the wavelength of the source?
