(a) The labelled diagram is shown.
(b) The refractive index of diamond is 2.42. Refractive index of diamond is the ratio of the speed of light in air to the speed of light in diamond.i.e.,
μ=  
Speedoflightindiamond
Speedoflightinair
  
and, the ratio of these velocities is 2.42. i.e., This means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in air. In other words, the speed of light in diamond is  
1/2.42
times the speed of light in vacuum.
Explanation:
a) Draw and label the diagram given :
   (i) Incident ray
   (ii) Refracted ray
   (iii) Emergent ray
   (iv) Angle of reflection
   (v) Angle of deviation
   (v) Angle of emergence
(b) The refractive index of diamond is 2.42. What is the meaning of this statement in relation to speed of light?
 
        
             
        
        
        
Answer:
force F = 1.66 ×  N
 N
Explanation:
given data 
proton and an electron = 865 nm
solution 
we get here force that is express as 
force F = k q1 q2 ÷ r²      ......................1
put here value and we get 
force F = 9 ×  ×
 ×  
    
force F = 1.66 ×  N
 N
 
        
             
        
        
        
Answer:
60-100
Explanation:
A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.
