Compare the color of light emitted by the spectrum tube without looking in the

spectroscope to that observed through the spectroscope. Can you predict the spectral pattern by looking at the tube with only your naked eye?

Without looking in the spectroscope, the color of light emitted by the spectrum tube appears as a single color. This is because the light is not being dispersed into its component colors. When looking through the spectroscope, the light is dispersed into its component colors, forming a spectrum of colors. It is not possible to predict the spectral pattern by looking at the tube with only your naked eye.
