No....Dispersion doesn't occur ,since medium 1 and 2 are same ..and hence they have same refractive index.
Moreover the speed of all the wavelengths is same in vacuum (or air),hence they travel as a single beam. But the speed of different wavelengths is different in glass (media),the refractive index depends on the wavelength and hence a spectrum is seen . If the hollow prism is filled by some other media ,there will be a chance of spectrum formation ,depending on media.The variation of refractive index with wavelength may be pronounced in some media than the other.
hope this helps you.....:)

Yes a beam of white light disperses through a hollow prism but the dispersion is very little. The dispersion will be due to the finite thickness of the prism shell.
