The speed of any wave is equal to the product of frequency x wavelength.
Speed = (frequency) x (wavelength) = (2) x (2) = 4 meters per second.There's not enough information to calculate 'velocity'.
1.5 Hz =1.5 1/sec 1.5/sec * 2m= 3m/sec
Speed = (wavelength) x (frequency)Speed = (2 meters) x (10,000 per second) = 20,000 meters per second
For any wave, the speed of the wave is the product of its frequency and of its wavelength.
2m*0.3Hz=0.6m/s

The speed of any wave is equal to the product of frequency x wavelength.
Speed = (frequency) x (wavelength) = (2) x (2) = 4 meters per second.There's not enough information to calculate 'velocity'.
1.5 Hz =1.5 1/sec 1.5/sec * 2m= 3m/sec
Frequency = speed/wavelength = 300,000,000/2 = 150,000,000 = 150 MHz. (The ham-radio band from 144 to 148 MHz is usually called the "two-meter band".)
Frequency = (speed)/(wavelength) = 12/2 = 6 per second = 6 Hz.Note:The question doesn't give enough information to describe the velocity. "12" is nota velocity, but it can be a speed, and we've assumed that it is. Fortunately, 'speed'is all we need to answer the question.
Speed = (wavelength) x (frequency)Speed = (2 meters) x (10,000 per second) = 20,000 meters per second
Frequency can be calculated using Velocity/Wavelength. 3x108m/s / 3x10-2m = 1010s-1 So that's 1010 Hz, or 10GHz.
The speed of 2m/s is the time covered to get to 2m in a second.
Velocity is very similar to speed, but it is a vector so it has direction. eg, the speed of a bike might be 2m/s (ignore the numbers: I'm making that bit up) but its velocity will be 2m/s North or 2m/s SW.
