Astretched string is 2.11 m long and has a mass of 19.5 g. when the string is oscillated at 440 hz, which is the frequency of the standard a pitch that orchestras tune to, transverse waves with a wavelength of 16.1 cm travel along the string. calculate the tension in the string.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
