Dear moderators, how I wish this thread could be move to the Chemistry Forum. May you help me do that please?
How many users in this forum know; have heard, have seen or have come in contact with a wine known as palmwine? The wine is naturally obtained from...
Caesium metal of work function 2.0 eV is illuminated with radiations of wavelength 5.0\times10^{-7}m. Calculate the: (i)threshold wavelength of the...
Use the lens formula to show that f^2 = ab. f^2 = square of focal length. a = object distance. b = image distance. I need help please. The lens...
Thank you.
But fo is threshhold frequency. Isn't it?
Since threshhold wavelenght and frequency are not the same. If am asked to compute the threshhold wavelenght, I use E=hf=\frac{hc}{\lambda} If am...

One more question: Is there anything like threshhold wavelenght? If there is, does threshhold wavelenght and threshhold frequency mean the same...
I was even thinking that frequency and wavelenght are the same thing. Thank you for the clearance.
You are confusing me by saying yes and no at the same time. From the my post, you saw that K.E. Increases with the increase in frequency. Based...
But looking at this:OTHER FUNDAMENTAL LAWS OF PHOTO ELECTRIC EMISSION from http://www.citycollegiate.com/physicsXII_17b.htm It looks as if the the...
In a photoelectric emission, a faint blue light of wavelenght 5.0\times10^{-7}m and a bright red light of wavelenght 7.0\times10^{-7}m are...
Yes, am very confused as wether to write x \propto m^2 + n^3 or x \propto m^2n^3
I WANT TO WRITE: X varies jointly as the square of m and the cube of n. SOMEBODY HELP PLEASE.
X varies jointly as the square of m and the cube of n. When x = 9, m= 3/4 and n = 1/2. Determine the relationship between x, m and n. Is it correct...
What I want to ask is: What could have been the best way to show the proportion? Is it like this /alpha m^2n3
Separate names with a comma.
