AI Thread Summary
The discussion addresses whether 449-nm blue light can eject electrons from silver, which has a work function of 4.74 eV. The calculation shows that the energy of the blue light is 2.77 eV, derived from the equation E = hc/lambda. Since 2.77 eV is less than the work function of 4.74 eV, the conclusion is that the blue light will not eject electrons from the silver metal. The response confirms the correctness of this conclusion.

Homework Statement



Would 449-nm blue light eject electrons from silver metal with a work function of 4.74 eV?

Homework Equations



E = hc/lamba

The Attempt at a Solution



E = [(6.63*10^-34 J*s)(3.00*10^8 m/s)]/(4.49*10^-7 m)
= 4.42*10^-19 J

4.42J/1.60*10^-19 J/eV
= 2.77 eV

Since 2.77 eV is less than the work function the blue light would not eject electrons from the silver metal.

***is this correct?? thanks for the help in advance! :)

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

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 hanging mass'

Thread 'A cylinder connected to a hanging 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...
