1. An oscillator consists of a 0.5 kg mass connected to a spring. When set to oscillation with an amplitude of 35 cm, the oscillator repeats its motion every 0.5 seconds. Determine (a) the period (b) the frequency (c) the angular frequency (d) the spring constant (e) the maximum velocity (f) the magnitude of the maximum force on the mass of the spring. 2 . 8.25 Hz water waves propagate from deep waters with a speed of 42 cm/s to shallow waters at a speed of 31.5 cm/s. The angle of incidence is 30.Determine (a) the wavelength in the two media (b) the angle of refraction in shallow water. 3. Two slits have green light of wavelength 5 . 25X183' m passing through them. The interference pattern was observed at a distance of 1.75 m. The distance from the first dark line to the ninth dark line is 10.2 cm. Determine (a) the distance between adjacent dark lines (b) the distance between the slits ((2) whether to use light with a larger or smaller wavelength in this situation to produce a pattern of closely spaced lines?
