A wave of wavelength 52 cm travels with frequency 400 Hz. What is the speed of the wave? Show work. Please help me...
speed = wavelength * frequency
To find the speed of a wave, you can use the equation:
Speed = Wavelength x Frequency
In this case, the given wavelength is 52 cm and the frequency is 400 Hz.
Substituting these values into the equation, we have:
Speed = 52 cm x 400 Hz
Now, we need to convert the units of wavelength from cm to meters, since speed is typically measured in meters per second.
1 meter = 100 cm, so 52 cm = 52/100 m = 0.52 m
Now, we can calculate the speed:
Speed = 0.52 m x 400 Hz
= 208 m/s
Therefore, the speed of the wave is 208 m/s.
