A wave travels through two media. In medium 1, its speed is 400 m/s and wavelength is 2 m. In medium 2, the speed is 600 m/s. The wavelength in medium 2 is:
A transverse wave on a string is represented as y = 10sin(πx/2 - 4πt), where x and y are in cm and t is in seconds. The particle velocity at x = 1 cm and t = 0 is:
A tuning fork of frequency 512 Hz is vibrating above a resonance tube filled with water. As water level is lowered, resonance first occurs at length 16 cm. The speed of sound is:
A wave pulse on a rope travels from a denser to a lighter medium (from thin to thick rope). The reflected pulse:
A wave undergoes constructive interference with another identical wave. The resulting amplitude is A₀. If one wave's amplitude is reduced to half, what is the new resultant amplitude for constructive interference?
