^__^ Thank you extremely much! I was struggle in this question because I was confuse myself with other concepts. But now I'm much more confident in it.
Yes, I will definitely review my sentences (English is my second language so I often make it as simple as possible before tiding it up.)

Use Max Planck's quantum theory to explain the following behavior of photoelectrons.
i) Low-intensity light does not release any photoelectrons. What will happen if the light is made brighter? Explain your reasoning.
ii) Low-intensity light releases photoelectrons...
Δtm = Δts/√(1-v2/c2)
Δtm = Δts/√(1-v2/(2v)2)
Δtm = Δts/√(1-(1/4))
Δtm = 3.1x107/√(1-(1/4))
Δtm = 35795716.69
Correct?
If this is correct, then it supports the fact that time dilation happens a lot more when matter approaches the speed of light. In this situation since speed of light is reduced...
Thank you guys for the help! When I saw 3 X 10^3 I didn't know what it was and thought maybe it was a set value that i forgot to write in my notes.
Also, would you guys happen to know how the person got the value "1x10^-6" for question B?
I tried to solving for "c" in the equation Δtm =...
1. The problem statement,d all variables and given/known data
Two atomic clocks are synchronized. One is placed on a satellite which orbits around the Earth at high speeds for a whole year. The other is placed in a lab and remains at rest with respect to the earth. You may assume both clocks...
Yes I did. I got some help from our textbook but I did not want to plagiarize it. I use my own words as much as possible without changing any of the theories. Yes I do, for the most part I understand the concepts is just my english structure can sometimes mess up what I want to say when i write...
Homework Statement
Lenses often contain thin coatings to reduce reflections and UV radiation. Explain how this works.
Homework EquationsThe Attempt at a Solution
To reduce reflections on lenses, known as back-glare, they are often coated in what is called anti-reflective (AR). The AR causes...
Homework Statement
Choose a technology such as MP3 players, laser, medical imaging, or another that interests you (Other than the cell phone). Research the internet and find out how it is related to the physics of light and waves. In approximately 100-150 words, write a paragraph explaining...
Yeah, my sentences are quite repetitive but I did not want to fix it up, yet, as I wanted to ensure my answer was correct. So just to make sure, should I change anything? (Other than improving the sentence structure.) Or should I add in that third possibility?
Homework Statement
Imagine that you are conducting an activity with laser to create an interference pattern. Use the appropriate equations to predict two ways to change the interference pattern in order to have closer fringes. Explain your predictions.
