Wavelength and frequency have a reciprocal relationship. If one doubles, the other halves.
        
                    
             
        
        
        
Answer:
The ice melts mass is:

Explanation:
Kinetic Energy  



Heat gained by ice= mass(g) x 80 cal 
( 1 cal = 4.184 *10^7er or g cm^2/ sec^2)
Assuming no loss in heat,  in the motion so both continue with temperature 0~C 
To find so the mass (gm) of ice melted 


 
        
             
        
        
        
The wavelength of the third line in the Lyman series, and identify the type of EM radiation
In this series, the spectral lines are obtained when an electron makes a transition from any high energy level (n=2,3,4,5... ). The wavelength of light emitted in this series lies in the ultraviolet region of the electromagnetic spectrum.
1 / lambda = R(h)* ( 
 -   
)
                  = 109678 ( 
 -  
 )
                  = 109678 (8/9)
    Lambda = 9 / (109678 * 8 )
                   = 102.6 * 
 m = 102.6 nm
