What color is closest to the central maximum?
Violet and blue will be seen closer to the central maximum — then green and yellow and orange and finally red, farthest from the white central maximum. a) is a diffraction source.
Why is diffraction grating better than a prism?
However, a diffraction grating is less sensitive to the color of the light and can be made to spread colors over a larger angle than a prism. The glass in a prism is clear to visible light, but it absorbs and blocks light in the infrared and ultraviolet part of the spectrum.
What is difference between grating and prism?
The prism achieves dispersion due to the difference in the material refractive index according to the wavelength. However, the diffraction grating uses the difference in diffraction direction for each wavelength due to interference. Exploits diffraction from a reflective surface with a regular grating structure.
What color Diffracts the most?
red
Is the rainbow a sign from God?
In the Bible’s Genesis flood narrative, after creating a flood to wash away humanity’s corruption, God put the rainbow in the sky as the sign of his promise that he would never again destroy the earth with flood (Genesis 9:13–17):

Why is a rainbow curved?

What does a rainbow promise?

What causes a rainbow?
When sunlight hits a rain droplet, some of the light is reflected. The electromagnetic spectrum is made of light with many different wavelengths, and each is reflected at a different angle. Thus, spectrum is separated, producing a rainbow.
What does the Ark represent?
The Ark represented God’s tangible presence among His people and was God’s throne on earth. It was the centerpiece of Jewish life and the epicenter of Israel’s religion.
