Determine the amplitude and wavelength of the wave. AMPIItUdS wavelength =
See it on the paper →Calculate the wavelength of the P-wave. wavelength = m P-waves travel at 6200 m / s in rock. The frequency of a P-wave is 12 Hz. (ii)
See it on the paper →Infrared radiation emitted by the lamps includes radiation with a wavelength of 0.75 mm. Calculate the frequency of this infrared radiation. frequency = Hz
See it on the paper →What is the name of the distance between two consecutive crests of a water wave?
See it on the paper →In air, the frequency of the sound from the horn is 250 Hz and the wavelength is 1.32 m. Calculate the speed of sound in air. speed of sound in air = m / s
See it on the paper →Which diagram represents a wave with twice the frequency and half the amplitude of the wave in diagram 1?
See it on the paper →Difficulties included using the wrong value for the speed of electromagnetic radiation and not converting the units from mm to m for the length. This resulted in a value of 4.0 x 108 Hz being frequently seen.
