Analysis of an interference effect in a clear solid shows that the wavelength of light in the solid is 434 nm. Knowing this light comes from a He-Ne laser and has a wavelength of 633 nm in air, is the substance fused quartz or flint glass?

If 2 different solids have the same masses but different volumes, how will their densities compare? a. the solids will have the same densities. b. the solid with lower volume will have a higher density. c. the solid with greater volume will have a higher density. d. the solid with greater volume will have double the density of the solid with the lower volume.
