Okay so today i sat a AS level physics paper and after finishing the exam i looked threw the equation booklet and decided to do some manipulation and i came up with this and was wondering what you guys think of it. Im confused!! :)(adsbygoogle = window.adsbygoogle || []).push({});

E=hc/λ AND λ=h/mv

subbing in gives E=hcmv/h which is E=cmv

conservation of energy...

cmv=1/2mv^2

2c=v

how can velocity = 2*speed of light?

Thoughts?
