A light wave travels from a denser medium (refractive index 1.5) to a rarer medium (refractive index 1.0). If the angle of incidence is 30°, what is the angle of refraction?
A standing wave is formed on a string with equation y = 2cos(πx)sin(100πt) cm. What is the wavelength?
An organ pipe closed at one end has fundamental frequency 200 Hz. What is the frequency of the next possible resonance?
A progressive wave has amplitude 5 cm and wavelength 20 cm. Two points on the wave separated by 10 cm have a phase difference of:
A source emits sound with intensity 10⁻⁸ W/m² at a distance of 1 m. Assuming spherical spreading, what is the intensity at 10 m distance?
A tuning fork of frequency 512 Hz is held above the open end of a resonance tube containing water. The tube is gradually filled with water and resonance is first observed when the water level is 16.2 cm below the open end. Taking speed of sound as 340 m/s, what is the effective length of the air column at first resonance and why?
