A spacecraft is traveling at almost the speed of light towards Alpha Proxima, the closest star outside of our solar system. A spectrometer focused on that star is looking at the wavelengths of light it gives off. Compared to the color observed from Earth, what would you expect to see from the speeding craft?  a The color of light would stay the same.  b The light would shift more to white.  c The light would shift more to blue.  d The light would shift more to red.

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
