transistors? (1 Viewer)

[Haku]

is transistors part of the syllabus, would it be tested?

and also the experiment on the release of photoelectrons, where u use that opposing current thingy.

· Gather, process and present secondary information to discuss how shortcomings in
available communication technology lead to an increased knowledge of the properties of materials with particular reference to the invention of the transistor

· Identify data sources, gather, process, analyse information and use available evidence to assess the impact of the invention of transistors on society with particular reference to their use in microchips and microprocessors

I should mention that these, particuarly the second, have not been tested yet

i believe thats quite important..isnt that what einstein did in his main investigation into the photoelectric effect, where he discovered owrk function and the formula...

E = % + KE

nb: % is work function

 

[Haku]

but i don;t think its in the new syllabus though. but still good to know it.

 

[Captain Gh3y]

The terms Work function, cutoff frequency and kinetic energy of photoelectrons do not appear anywhere in the syllabus. However, they were all part of Einstein's explanation of the photoelectric effect, which IS in the syllabus.

There have never been any HSC questions asked on work function and photoelectrons, etc, so I for one really don't know whether they could ask or not.

Transistors:
An example of an application question based on this, like you asked about:

John Bardeen discovered the transistor effect in the Bell Telephone Laboratories. Propose arguements, he would have used to Bell and other telephony companies to change their infrastructure to transistors.

Spoiler

So it wouldn't be good enough to just list advantages but put them in the context of financial and expansion of business.

Photoelectric Effect experiment
You will not be asked to describe the experiment but it may still be used as stimulus material, for you to recognize the cut-off frequency, work function or calculating plank's constant etc.

holy, mongeril, do u think they can ask that???

 

[helper]

Which, the Transistors or Photoelectric effect?

 

[richz]

bardeen one

It isn't any harder than the Westinghouse question, where if you just listed advantages of AC and disadvantages of DC you couldn't obtain full marks.
You just need to put your list of advantages from the dot point in the right form.

which question are u referring to? totally lost

and do u need to know the philip leonard experiment?

I am refering to the question 24 in the 2004 HSC and the one I typed earlier in this thread

No you no longer need to remember Lenard's experiment.
