wavelength In the first diagram the wavelength is much smaller than the aperture. An example is light coming in through a window and forming a beam of light across the room. In the second diagram, the wavelength is similar to the size of the aperture. Ocean waves spread out like this when they enter a harbour.
1. Violet light has a wavelength of 4.10 x 10-12 m. What is the frequency? 7.31 × 1019 Hz. 2. Green light has a frequency of 6.01 x 1014 Hz. What is the wavelength? 4.99 × 10-7 m. 3. What is the wavelength (in meters) of the electromagnetic carrier wave transmitted by The Sports Fan radio station at a frequency of 640 Hz? 4.7 × 105 m. 4.
The wave nature of light is described by the equation c = λ·ν, which relates the speed of light (c, meters per second, m·s-1) to the wavelength (λ, lambda, meters, m) and the frequency (ν, nu, Hertz, Hz, s-1); because the speed of light is a constant in a given medium, wavelength and frequency are inversely proportional. 3.
Label that diagram with “n=3 to n=2,” list the appropriate wavelength, and color the wavy line with the correct color as on the bottom of page 1 to represent the appropriate corresponding color of light emitted.
