Graded discussion board (GDB) Physics (PHY101) Last Date 6th August 2014

Graded Discussion Board for the course PHY101 (PHYSICS) will start on Tuesday 5th August 2014.

You should remember that you have to post your comments about the discussion title within the time.

This discussion board will be closed on Wednesday 6th August 2014.

No comment about the Discussion topic should be posted on the regular Moderated Discussion Board which is created for each lecture.

The topic for the discussion is:

Is it true or wrong that all wavelengths (colors) of light refract at the same angle when crossing the interface between different media. Either yes or no explain with solid reason.

Elaborate your answer by giving a solid reason, give mathematical calculation (proof) where necessary.

Also you should remember that this Discussion is graded and maximum marks for this Graded Discussion Board 5% and it will count in your final Grade. So these marks may be helpful for you to get A grade from B and B grade from C and so on.

In the end you should also know that we will not extend the date of discussion in any case.

• Plagiarism is prohibited that is why you are advised to avoid copy/paste from internet etc, if found at any stage will be graded as zero marks.

·     All students are directed to use the font face Time new Roman and Font size 12.

• Don’t use colorful back grounds in your solution.
• Use Math Type or Equation Editor etc for mathematical symbols.
• It also suggests you to keep your GDB solution safe from others. No excuse will be accepted by anyone if found to be copying or letting others copy.

koi to discuss kro plzzz......

plz discusss it
koi to solution do

koi to solution do

it is wrong statement:In general, the speed of light in a medium depends both on the medium and on the wavelength of the light. Another way of saying it is that a medium's index of refraction varies with wavelength. This is why a prism can be used to split up a beam of white light into a rainbow. Each wavelength of light is refracted through a different angle.

No white light is the composition of seven different colors every color has its own wavelength hence have different ability to bend in the different mediums

Please Discuss here about this GDB.Thanks

Our main purpose here discussion not just Solution

We are here with you hands in hands to facilitate your learning and do not appreciate the idea of copying or replicating solutions.
