Studies have shown that congenital amusia is a deficit in fine-grained pitch discrimination and that 4% of the population suffers from this disorder.
Ultraviolet (UV) light is light with higher frequency (lower wavelength) than visible light. UV light has frequencies ranging from 8*1014 to 3*1016 Hz (800 THz to 30 PHz) and wavelengths from 10-8 m to 3.8*10-7 m (10 nm to 380 nm). Prolonged exposure to UV light causes sunburn and can cause skin cancer.
In general, FM radio refers to radio that is broadcast using FM, or frequency modulation, as its modulation scheme. Frequency modulation is the shifting of the frequency of th â¦ e transmitted signal above and below an assigned center frequency or carrier frequency to impress the signal on the carrier.
