Figure above shows an interference pattern of two coherent waves. Which of the positions does constructive interference occur?
A point where constructive interference happens is called a
Figure above shows an interference pattern of two coherent water waves. Which of the points among P, Q, R and S are nodes?
Figure above shows an interference pattern of two coherent waves. The point X is
Figure above shows an interference pattern of two coherent waves. Which of the line is an anti-node line?
Two round dippers separated by a distance of 6.0 cm is connected to a vibrator to produce two coherent sources of spherical waves. The distance between the sources and where x is measured is 20.0 cm. If the distance between two successive anti-node lines is 3.0 cm, determine the wavelength for the spherical wave.
Figure above shows 2 spherical dippers of 4 cm apart in a ripple tank. The dippers produce waves of 5cm wavelength. Find the distance between 2 anti-node lines which is 20cm from the dippers.
Figure (a) shows the arrangement used to demonstrate interference of sound waves, the audio signal detected at point A and B are shown. Which of the following statements is true?
Figure (a) shows the arrangement used to demonstrate interference of sound waves. The distance between the 2 speakers is 2 m. A microphone is used to detect the audio signal 20 m in front of the speakers. Given that 2 consecutive loud sounds is detected at A an B. Find the frequency of the audio signal. (Speed of sound in air = 330 ms-1)
Two speakers is placed 1.5 m apart. An audio signal generator is adjusted to a frequency of 600 Hz. When a student walks 3.0 m in front of the speakers, he gets to hear four loud sounds successively in a distance of 3.3 m. Calculate the wavelength of the sound wave
