AI Thread Summary
To rearrange the equation Eph = hc/lambda to solve for lambda, start by multiplying both sides by lambda, resulting in Eph * lambda = hc. Next, isolate lambda by dividing both sides by Eph, giving lambda = hc/Eph. This algebraic manipulation is straightforward and essential for solving linear equations. For additional guidance, a tutorial on linear equations can be found in the Math and Science learning materials section of the forum. Understanding these steps is crucial for exam preparation.

Please can someone show me the steps needed to go about rearranging the equation Eph = hc/lambda to make lambda (the wavelength of the light) the subject? I'm totally stuck and I have an exam in the morning. I suspect this is one of the questions that will come up. I know it should be simple but I'm just not getting it. Any and all help is appreciated.

I am assuming that the ph on the left side of the equation is a subscript for photon and that the equation looks like this.
E_{ph}=\frac{hc}{\lambda}

I also assume that by "make(ing) lambda (the wavelength of the light) the subject" you mean that you want to solve the equation for lambda.

This is an algebra question. I found a link in the Math and Science learning materials section of this forum:

You might want to look at tutorial 14. Linear Equation in one variable.

To get you started, what would happen to your equation if you multiplied both sides by \lambda ?

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'

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...
