Final answer:
Without the full context, it's difficult to provide an accurate calculation for the separation distance. The numerical values 1.1 and 1.4 suggest a proportionate increase in separation distance if other variables remain constant. This question is likely referring to dispersion in physics.
Step-by-step explanation:
The question seems to be asking about the difference in the separation distance for two different hypothetical situations where the dispersion formula hc/d is used with different numerical values, 1.1 and 1.4. This could relate to a physics context, where hc stands for the product of Planck's constant (h) and the speed of light (c), and the d might refer to some characteristic distance or parameter in a given physics problem. The dispersion generally would refer to the separation of light into its component wavelengths due to differences in refractive index, such as in a prism or another optical system. Without more context, it is difficult to provide a specific answer, but conceptually, if 'd' remains constant, increasing the value of the numerator from 1.1 to 1.4 would result in a greater separation distance. However, the provided information appears to be missing the necessary context to calculate a precise separation distance.
