Question

Define the term effective bandwidth of a filter.

Short answer

The wavelength range that a filter isolate is its effective bandwidth.

Step-by-step solution

Step 1:Given information

Explain the effective bandwidth of a filter.

The effective bandwidth

Monochromators or filters are special devices that help in restricting the radiations that are being measured from a wide range to a narrow band. These are used in spectroscopic instruments.

From a broad spectrum, these filters or monochromators isolate the wavelengths that are desired. This wavelength range which the filter or monochromator isolates is referred to as its effective bandwidth.
