Answer:
WAVELENGTH
Question: What is the wavelength of the wave with a frequency of 3x10^{9}3x10
9
Hz?
Formula: λ = ν/f
where; lambda (λ) = the wavelength of the wave
ν = velocity, or the speed of light c = 3x10^{8}3x10
8
m/s. and;
f = the frequency of the wave equals 3x10^{9}3x10
9
Hz or per second
Solution:
λ = ν/f = \frac{3x10x^{8} m/s }{3x10^{9}/s }
3x10
9
/s
3x10x
8
m/s
= 0.1 meters or 1x10^{8}1x10
8
nanometers
Definition of terms:
Wavelength - In Physics, a wavelength spatial period or distance between the periodic wave's highest p o i n t (adjacent crest). In other words in is the distance separating two consecutive p o i n t s of two waves.
Frequency - The frequency of the wave is the number of wave occurence per unit time, usually in seconds. Also measured in Hertz or Hz means per seconds 1\s.
Velocity - Pertains to the speed of the wave, usually light. The speed of light is equal to 3x10^8 meters per second.
