Quick question, just want to clear out something

Question

somy · Answer

is it because for a stationary wave to form you need minimum of 2 waves?

@KissMyAxe @ParthKohli @thushananth01

anonymous · Answer

okay same here use mathematics 
u know that 
$$\frac{\lambda}{2} \times 1 (loop) = x(wire length)$$
$$\lambda = 2x$$
Hence 
$$v = f \lambda$$
$$\frac{v}{2x} = f$$-----1
this is the first equation 

Now you need two loops so form an equation...why dont u try :)

anonymous · Answer

clarify your doubts

anonymous · Answer

@Somy  did u try?

somy · Answer

yup thnx i originally did speed=frequency* wavelength 
and i just thought that i'll need 2 waves for stationary wave to form :D

somy · Answer

yes i did)

somy · Answer

i need 4 loops thats why im getting 2 waves

anonymous · Answer

oh okay :)

anonymous · Answer

Did u get the answer

somy · Answer

yes i did) @KissMyAxe

anonymous · Answer

Well i did it like this and it worked:
1 loop frequency is equal to f therefore for two loops it will be 2f :) ratio method

anonymous · Answer

Hey guys :)
I just want to know when they say the word 'loop' I don't really know how to imagine the wave to look like, any ideas anyone?

anonymous · Answer

A loop has two nodes and antinodes between the node

what you see is a wave of wavelenth lambda, and therre are 2 loops
