More Great Information on Color Beam:
Interior for a Multi purpose room by Bharat Gandhi
There is no right or wrong way to interior decorate a house, but to get good results one has to go into detail of pre-planning and planning of space. With the availability of alternatives and multi-choice of designs and products for an interior when we start planning for a new house or redecorating the existing interior one can be very confused. To achieve professional look for your interior little devotion and a proper analytic mind can go long way.
Today Television set, perhaps more than any other invention is responsible for changing the interior of the modern houses. In fact it has given rise to a brand new room- the family room or an audio video room. Normally most of the family members are confused about the actual function of the living room. Even a five year old kid knows with certainty that family room is for watching television.
So the main function of a family room is to view a television. Hence the television should be the focal point in the interior and the sitting system should revolve round it however, a circle of seating systems around it would lack in aesthetic of the room, and creating a more balanced arrangement also means disadvantageous viewing angle for some. To overcome this problem of uncomfortable viewing angle it is advisable to have sitting system which is composed of independent comfortable chairs which can be moved as required in the interior, some corner in interior can have Indian type of sitting with lots of soft cushion for comfort.
The use of this room will be maximum, wear and tear will also be maximum so to overcome it, it is advisable to use strong and study designed furniture and furnishing fabric, the upholstery used on this sitting system should be of material with synthetic blend, tightly woven, mild to dark colored, preferably patterned and stain resistant. The flooring should never have carpet but wood or laminated floor would be ideal.
Window dressing should be of a dark color, thick fabric so as to avoid reflection on the tube plus to add to the acoustical effects. Lighting is exceedingly important factor in this room. Subdued light just for the purpose of proper visibility would be more than adequate but if this room interior also doubles up e.g. study room or library then it has to be properly lighted with fluorescent lights.
Today dedicated room for a librarian have become things of past but if still one wants to have library in the family room one can have a properly designed book shelf or unit and one or two reading chairs with footrest to make one tempted to read. Too soft and comfortable chair in interior may make one sleep rather than read. A good antique lamp shade can add old charm to the interior.
This room can also double up as study room in the day time and audio /video room in the evening. If one is using this room for study then proper furniture for the use has to be designed like a comfortable study table which can house a computer and allow minimum two people to use the same at the same time i.e. student and the teacher, adequate storage system for books should always be provided the interior.
Today people are becoming more and more religious and a need for a Pooja room has become a necessity. So if one wants it a small Pooja area can be created in this room.

Physics Problem!?? Help!!!?
A) A very Narrow Beam of White Light is incident at 41.30 onto
the top surface of a rectangular block of int glass 14.5 cm
thick. The indices of refraction of the glass for red and violet
light are 1.639 and 1.664, respectively.
Calculate the dispersion angle (i.e., the difference between
the directions of red and violet light within the glass block).
B) How wide is the beam when it reaches the bottom of the
block, as measured along the bottom surface of the block?
C) When the rainbow-colored beam emerges from the bottom
of the block, the exiting rays of light are once again parallel.
Calculate the distance between the exiting red and violet rays
(i.e., the thickness of the rainbow).
A) Using Snell's Law we have n_a *sin(θa) = n_b*sin(θb)
so for red light we have
1*sin(41.30) = 1.639*sin(θb)===> θb = arcsin(sin(41.30)/1.639) = 23.746o
and for violet θb = arcsin(sin(41.30)/1.664) = 23.368o
So the dispersion angle is 23.746 - 23.368 = 0.378o
B) Using trig we see that the violet beam strike the bottom of the glass at 14.5cm*tan(23.368) = 6.265cm
and the red beam strikes at 14.5cm*tan(23.746) = 6.379cm
So the beam is 6.379 - 6.265 = 0.114cm wide
C) when the beams leave the glass they both will be refracted back at 41.30o
So the distance across the beam will be the separation distance times the cos(41.30o)
= 0.114cm*cos(41.30) = 0.0856cm
