Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
It's 2, with same length-unit as the one in the speed
Period = reciprocal of frequency ( 1 / frequency ) = 1/50 = 0.02 second = 20 milliseconds
wavelength = speed / frequency Wavelength should be expressed in meters (m), speed in meters per second (m/s), and frequency in hertz (Hz). I assume by "ms" in the question you actually mean "m/s" since the former is "milliseconds" (a measure of time) and the later is "meters per second" (a measure of speed). 1000 / 50 = 20 meters
The velocity of a wave can be calculated using the formula: velocity = frequency * wavelength. Plugging in the values, the velocity of the wave would be 1000 meters per second.

50 / 2.5 = 20, same units as numerator of velocity
Increasing the wavelength by 50 percent will decrease the frequency of the wave by one-third. This is because frequency and wavelength are inversely proportional - as wavelength increases, frequency decreases, and vice versa.
Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
The wavelength of a wave can be calculated using the formula: wavelength = speed of wave / frequency. In this case, the wavelength would be 0.5 meters, as 50 m/s divided by 100 Hz equals 0.5 meters.
Convert the cm to meters, to have compatible units. Then use the fact that the frequency times the wavelength is equal to the speed of the wave. In this case, you can divide the speed by the wavelength, to get the frequency.
The speed of the wave can be calculated using the formula v = fλ, where v is the speed, f is the frequency, and λ is the wavelength. Plugging in the values, we get v = 5.0 Hz * 10 mm = 50 mm/s.
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
The wave speed can be calculated using the formula: wave speed = frequency x wavelength. Plugging in the values given, the wave speed would be 20 Hz x 2.5 m = 50 m/s.
