Its only given for the transverse wave which is 15 Hz

I think u r confused .. Which Question are You talking about.. Plz post the link!

Question 5 (b) can some one please show the drawing ?

Thought blocker I'm sorry if I'm bothering u a lot !
Thank u

Bhai it clearly mentions 0.25 t= 1/4 T! ?
And This is similar question to Another one.. which had the exact same thing!

Thanks! Now I get it

in 1/4 cycle antinode gets from highest point to zero. then in 1/4 it gets to lowest point then in 1/4 it gets to zero. then in 1/4 it gets back to max. so in one T it completes on cycle.


here is Suchal explanation

The time for one oscillation of point A on the rope is 0.20 s, now we have to add 0.05s
Hence, the wave would shift 0.25lambda towards right
Amplitude and wavelength is not changing

 

[Mohammed salik]

I didnt give the link for this one .And by the way m.s REJECTS high speed sorry .
β-particles have a range of energies
β-particles deviated by (orbital) electrons
β-particle has (very) small mass
(any two sensible suggestions, 1 each, max 2) B2 [2]
Do not allow β-particles have negative charge or β-particles have high speed [2] marks

HAha.. OK Thnx ANYWAYS.. i would still score 2 !

Could You please Drw it if u have time.. ! Wont it be at Equilibrium Poisition?

Only point A dear
Well I can't draw it, coz m lil busy so sorry. :'(
Temme if u dont understand...

I think like this.

 

[Thought blocker]

I think like this.

We just need to shift waves towards right with 0.25 lambda, no need to change wavelength nor amplitude

Question 6, part b.. (iii) ..

 

[Kamihus]

Anyone has list of estimates of the physical quantities?

 

[Snow Angel]

The Time period you mentioned here

but why would be a straight line after 0.005 s? please can u xplain. thnx

yes..
