Physics basics | frequency
wave = energy wave completes a cycle= a positive half and negative half, like like wave in water, when you blow it. frequency of a wave = number of completed cycle / any time interval = that many Herts 2 cycle / sec = 2 Hertz frequency. SPECTRUM (RANGE) The range of frequency for a given type of waves, sound waves, electrical waves, electro-mangnet waves. The range is defined by the starting and end frequency also refered as bandwidth(0-50 herts = BandC) WAVELENGTH The distance between two similar point of a given waves because signal strength can not only be defined by frequency, ie. how many wave cycle per sec , it also depends , how big the wave is (Wavelength) Lamda = C/ F , where c = speed of light 8 FM Radio frequency, ranges from 87 Mhz to 104 Mhz, i,e, the that many cycles per second, you if you want to catch a specific f wave you need tune your receiver to that level, so that you catch that wave only.
