The amplitude is the height of the wave. (B) A wave with a short wavelength (top) has a high frequency because more waves pass a given point in a certain amount of time. A wave with a longer wavelength (bottom) has a lower frequency. (Credit: Christopher Auyeung; Source: CK-12 Foundation; License: CC BY-NC 3.0(opens in new window))

How to Calculate Frequency From Wavelength. Rearrange the equation and calculate frequency from wavelength: f = v/λ. For example, find the wavelength of orange light with a frequency of 4.8×10 14 Hz. f = v/λ (but v is c for light) f = c/λ f = (3.00 × 10 8 m/s)/(4.8×10 14 s-1) f = 6.2 x 10-7 m = 620 nm. Wavelength to Frequency Chart
Possible Answers: Correct answer: Explanation: The velocity of a wave is equal to the product of the wavelength and frequency: We can rearrange this formula to solve for the frequency. Since microwaves are on the electromagnetic spectrum, their velocity will be equal to the speed of light. We are given the wavelength.
Figure 13.8 Because they travel at the same speed in a given medium, low-frequency sounds must have a greater wavelength than high-frequency sounds. Here, the lower-frequency sounds are emitted by the large speaker, called a woofer, while the higher-frequency sounds are emitted by the small speaker, called a tweeter.
Step 1: List the known quantities and plan the problem. Convert the wavelength to m m, then apply the equation c = λν c = λ ν and solve for frequency. Dividing both sides of the equation by λ λ yields: ν = c λ ν = c λ. Step 2: Calculate. 620nm ×(1m 109 nm) = 6.20 ×10−7 m 620 nm × (1 m 10 9 nm) = 6.20 × 10 − 7 m.
