How does the wavelength of light impact the storage capacity of optical media?
Shorter wavelengths allow for a greater storage density.
Longer wavelengths allow for faster read/write speeds.
Wavelength has no impact on storage capacity.
The color of the light determines the data format.
Forklaring
Shorter wavelengths allow for more data to be stored on the surface of an optical disc by reducing the size of the pits or marks used to represent data, thus increasing storage density.
