time period T = 1 ÷ frequency sec.
Wavelength = 2 cm.
Number of waves produced per second = 15/3= 5.
So Frequency = 5 Hz.
Speed of the wave = frequency* wavelength
= 5 * 2 = 10 cm/sec.
Wavelength = 2 cm.
Number of waves produced per second = 15/3= 5.
So Frequency = 5 Hz.
Speed of the wave = frequency* wavelength
= 5 * 2 = 10 cm/sec.
