How would I find the threshold frequency if the work function is 3.33eV? I know how to calculate minimum frequency.

How is the transistor an important advancement in physics?

oh wait nvm i got it lol

wait, according to the equation F=qvBsin theta ...can't there still be a magnetic force?

So, no forces?

If a charged particle moves at a constant velocity in a straight line through a region of space, is the electric field and/or magnetic field in the region zero?

If light is a wave then how come we can hear around a corner but not see around a corner?

I'm not sure those examples are the wave nature of light... maybe you could expand on one so I understand?

Well, I don't want to look specifically at colour or optics. I'm not sure how to explain it but I want to examine the benefits there is to society/technology of the wave nature of light, not so much optics...not sure if that makes sense.

In what other examples is the wave nature of light important in society and technology? One example is in DVD drive where different wavelengths can read different layers of the DVD.

For those familiar with the monkey and hunter theory, could you direct me to any site or do you know the mathematical proof to actually show that it's true? http://www.cwru.edu/artsci/phys/courses/demos/monk.htm

oh man...too advanced for me... Can somone just tell me if as the radius increases the period is longer or something?

For centripetal acceleration, what is the relationship between the radius and the period?

Yeah sry, turns out they were side by side...I was overcomplicating it :redface: Thanks for your help guys.

No friction between mass and ground. There's no picture...but anyways if the mass isn't on the top then I assume they're side by side b/c I haven't been able to get the answer. How do I find the force if they are side by side?
