Answer: The redshift occurs because the starts are moving away from the earth.

Explanation:

Every object emits wavelength from its body. When it comes to universe there are some visible light emitted by the stars and other objects in galaxy.

If a star is moving towards the sun then it emits a shorter wavelength compared to the source which is at rest. This is blue in color called as blue shift.

But when it comes to stars they move away from the earth and hence emits longer wavelength called as red shift.

As the object it at rest it more towards the blue side and when the objects starts moving it starts moving towards the red side in the visible spectrum.

So, when the starts moves away from the earth it forms a Redshift.

vesna_86 [32]

Answer:

D. 1×10⁻⁸ M

Explanation:

[H⁺] [OH⁻] = 10⁻¹⁴

(1×10⁻⁶) [OH⁻] = 10⁻¹⁴

[OH⁻] = 1×10⁻⁸

Which property of light would provide evidence for the idea that light is a wave?

Lena [83]

Color property of light would provide evidence for the idea that light is a wave

<h3><u>Explanation:</u></h3>

The reality is that light manifests practices that are representative of both waves and particles. Young proposed that light of varying colors was formed of waves possessing various lengths, a basic theory that is popularly believed today. In contradiction, the particle theory advocates envisioned that several colors were obtained from particles holding either various masses or moving at various speeds.

All waves are perceived to experience refraction when they transpire from one means to another means. Light, similar to any wave, is apprehended to refract as it transfers from one medium into another medium.
