. Choose the correct answer from the options given below:
Only
. Choose the correct answer from the options given below: Only
Text Solution
Verified by ExpertsThe correct answer is:
C
Checking each statement:
states 
has 24 protons, but the mass number is 24 and atomic number is 12 , so this is INCORRECT.
Using 
, which is CORRECT.
For 
and 
, since energy is inversely proportional to wavelength, 
, not 3:1 as stated, so this is INCORRECT.
For photons at 
, energy per photon is 
, giving 
photons for 1 J , which is CORRECT.
The incorrect statements are A and C .
