<p>I solve the question, but this is my first time ever taking physics. So I try to self learn it...
Here are the equation needed:
E = hf
C = λf
K=hf-ø
λ=h/p
ΔE=(Δm)c^2</p>
<p>Here is the question:
1. Find E if h=6.63 x 10^-34 J*S,λ= 450 nm, and c= 3x10^8 m/s. It said you need to convert λ ino meters before plugging in the number.
2. h is a constant, so it is always equal to the value in the prior problem. Assuming f is 4.2x10^14 Hz and ø is 1.3 x 10^-19J, calculate the value of K.
3. C is a constant, so it is always equal to 3x10^8 m/s. If the final state of m=3.4824 x 10^-27 kg and he intial state of m = 3,34829 x 10^-27 kg, find ΔE...</p>
