Ekta Yadav 7 years, 10 months ago

large because if a prism have large A then it's corresponding angles will be small and hence it will not show TIR (total internal reflection ). then we get spectrum of 7 colours.

Larger because light will travel more time inside the prism if angle of prism is more

Vineit Kumar Gupta 7 years, 10 months ago

Thanks a lot again actually i am very delighted that you know what it actually takes to maintain a simple website. after all we have to write or modify the scripts of the website and find a suitable host for it being a student you cant afford paid domains or hosts for your test projects you have to do research and find a option which is free and looks premium at the same time but people will always underestimate it and point different flaws and will criticise it , i know thats not perfect but you only tell who is perfect nothing exist as" perfect ",if you cant say good then dont atleast demotivate. Nothing is simple every thing holds a complex mechanisms inside so is the case with web development you have to test it on different servers and protect it from different script kiddies who always try to sql inject your site.
