Is this multiple choice? I would be able to help if I could see a list of options :-)
Answer:
Max kinetic energy for 340 nm wavelength will be 
Explanation:
In first case wavelength of electromagnetic radiation 
Plank's constant 
Maximum kinetic energy = 0.54 eV
Energy is given by 
We know that energy is given
, here
is work function
So 

Now wavelength of second radiation = 340 nm
So energy 
So 
Aluminum is a type of metal and that is a properties by the location of element
Answer:
If you are standing next to loud music you will feel yourself vibrating because resonance happens. When an object vibrating at or near the resonant frequency of a second object then it causes the second object to vibrate. This phenomenon is called resonance.
