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.

You have been taken to the emergency room. To get a constant update on your vital signs, equipment is attached to you, including a pulse oximeter. The pulse oximeter shines two LEDs on your finger to test how much oxygen is in your blood. One LED transmits in infrared (921 nm) and one transmits in visible red (632 nm). What are the frequencies of these LEDs? Red: (Hz) Infared: (Hz)
The dispersion curve of glass is the curve that describes how the index of refraction of glass changes as a function of the wavelength.
