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.
The FM radio band is from 88 to 108 MHz between VHF television Channels 6 and 7.The FM stations are assigned center frequencies at 200 kHz separation starting at 88.1 MHz, for a maximum of 100 stations.These FM stations have a 75 kHz maximum deviation from the center frequency, which leaves 25 kHz upper and lower gaurd bands to minimize interaction with the adjacent frequency band.he FM radio band is from 88 to 108 MHz between VHF television Channels 6 and 7.
