Aneon lamp produces what kind of visible spectrum?

Discrete

Explanation:

There can be many kind of visible spectrum. Some of them are as follows :Infrared,  Continuous , Blackbody  and Discrete.

A neon lamp produces discrete kind of visible spectrum. In this type of spectrum, the spectrum consists of different colors. It means that the neon lamp is made up of different colors or individual frequencies.

Hence, a neon lamp produces discrete visible spectrum.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
