BTEC Applied Science Unit 1 Physics Exam with Questions and Solutions Periodic time ANSWER the time taken (in seconds) for one complete cycle of a wave, vibration, or oscillation T = 1/f ANSWER time period, T (in seconds) and frequency, f (in hertz) Wave speed ANSWER the distance in metres (m) travelled by a wave in one second (s) wavelength ANSWER the distance (in metres) between two nearest corresponding points on a wave, e.g. the distance between two peaks (crests) frequency ANSWER the number of waves produced in one second or the number of waves that pass a point each second amplitude ANSWER the maximum displacement of a wave from its undisturbed position oscillation ANSWER a regular repetitive motion, e.g. a weight on a spring bouncing up and down, or a pendulum swinging backwards and forwards transverse ANSWER a wave in which the direction of oscillations is perpendicular (at right angles) to the direction of the wave
