What’s New?!
Hello PhysicsFans!
Let us explain what are the new developments at PhysicsFans.com.
Now we have changed the platform from Drupal to WordPress – as we thought that content is more important than the structure and other extensive capabilities offered by the Drupal system.
We are now in the process of tweaking the wordpress system to provide all the features and facilities (and some thing more!) we provided earlier with the drupal system.
How to use PhysicsFans.com now?
The first step is to join the site. When you register and then log in to the system, your account will be upgraded to contributor so that you can add blogs and participate on forums. You can post blogs, forum topics and replied to forum posts, but your posts and replies will appear on the site only after ADMIN approves your posts and Replies.
Please suggest more additions and desired features here. We are waiting to hear from you!

What do you mean by pure spectrum?
A specttrum in which there is no overlapping of different colours is called a pure spectrum.
How can we produce a pure spectrum?
For the production of pure spectrum, it is necessary that the slit should be narrow and the incident beam of light should be parallel. Then the emergent rays will be parallel to each other and will be focussed at a point by the telescope. Also, the rays of different wavelengths will be focussed at different points.
