frequency
No. Frequency is just a measure of "how often". It can be less than, equal to or greater than normal.
google it lazy bum. No, light waves are just that-- waves. The color of the wave is determined by it's frequency- normal light is white because it is low frequency. The frequency is how fast the light "waves". But a laser pointer has red light, which has a higher frequency, and therefore is only one color. Hope this helps!
Most people with 'normal' hearing can perceive sound up to 18,000 Hertz. The higher frequencies become less audible with age.
Infrasound has a frequency below normal hearing. Ultrasound waves have a frequency above the normal range of human hearing.
The frequency for the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
Because a dolphin's ear frequency is higher than a normal human's, so they have to have higher pitched whistles so the dolphins can here them better. Plus, high sound frequencies can travel underwater easier so dolphins can hear them.
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
