Physics And Measurement Question 261

Question: Dimensionally wavelength is equivalent to

Options:

A) $ \frac{E\sqrt{LC}}{B} $

B) $ \frac{E}{B\sqrt{LC}} $

C) $ \frac{B\sqrt{LC}}{E} $

D) $ \frac{B}{E\sqrt{LC}} $

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $ \frac{E}{B} $ = velocity = m / s and $ \sqrt{LC} $ = time period $ =s $
$ \therefore \frac{E\sqrt{LC}}{B}=m $ =wavelength
