free space wavelength sentence in Hindi

Examples

1. This can happen for example when the free space wavelength exactly equals the lattice spacing.
2. In this case the circumferential ( wavelength ) scaling must be used, remembering that this is the wavelength within the transmission line and may differ from the free space wavelength.
3. For example, at a frequency ? = 20 MHz ( free space wavelength of 15 m ) in a transmission line whose velocity factor is 2 / 3, the guided wavelength ( distance between voltage peaks of the forward wave alone ) would be ? = 10 m.
