Please help my son year 12 physics -- frequency and wavelength

AI Thread Summary
To find the wavelength from a frequency of 93.4 Hz, it's essential to know the wave speed in the medium. The relationship between frequency, wavelength, and speed is given by the formula: speed = frequency × wavelength. By rearranging this formula, wavelength can be calculated as wavelength = speed / frequency. Different mediums, such as air or water, will have different wave speeds, affecting the wavelength calculation. Understanding this relationship will help in solving the problem effectively.

my son is trying to find out how he can find an answer by being shown how to do the working out
he wants to find out what the wavelength is if he only has the hz if he is 93.4 hz how does he find out what the wave lenth is
thanks

Welcome to the PF, Martin.

When you show your son how to use Google to find the relationship between wavelength and frequency, what do you find?

BTW, that relationship will depend on the medium that the waves are propagating in. Sound in air has a different relationship versus light in air... :smile:

You need to know the speed of the wave as well. (frequency*wavelength)=speed.

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
