There are two proteins A and B to be visualized under fluorescence microscopy. Both of them are excited with same wavelength of light but A emits longer wavelength. Hence we can conclude that 

1. A is denser molecule than B

2. B is denser molecule than A

3. A is lighter molecule than B

4. B is lighter molecule than A
