Question

To produce a continuous absorption spectrum, pass the light through a filter, such as a piece of colored glass.

True or False?

Answer 1

False ....................... 

Answer 2

True

Step-by-step explanation:

Color filters are usually constructed using transparent pieces of dyed glass, plastic, or other suitable materials that have been treated to selectively transmit the desired wavelengths while restricting others.

The two most common types of filters in use today are absorption filters that absorb unwanted wavelengths

and interference filters that remove selected wavelengths by internal destructive interference and reflection. In any filter, a small amount of the incident light is reflected from the surface regardless of the filter construction and a small portion of the light is also absorbed. However, these artifacts are usually very minimal and do not interfere with the primary function of the filter.
