The value of densities of two diatomic gases at constant temperature and pressure are d1 and d2 , then the ratio of speed of sound in these gases will be

1. d1d2                                   

2. d2/d1

3. d1/d2                             

4. d1d2

2. Speed of sound in gases is given by 

       vsound=γPρ v1v2=ρ2ρ1=d2d1
