Answer:

The galaxy is moving closer to us

Explanation:

When there is a decrease in the wavelength of light which is being observed then it means that the object and observer are getting closer to each other.

When there is an increase in the wavelength of light which is being observed then it means that the object and observer are getting farther apart.

This phenomenon is called the Doppler effect.

Orange has shorter wavelength than red so the wavelength is getting shorter.

Hence, the galaxy is moving closer to us.

In singin' in the rain why was it that kathy seldon's title card (film credit) was taken off the screen?
Rufina [12.5K]

The story of Singin' in the Rain begins with a musical premiere in 1927, starring Don Lockwood and Lina Lamont. Even though they aren't, Lina thinks she and Don are a couple.

Kathy Selden was a talented stage actress who was later hired to record both Lina's speaking voice and singing voice for a new musical called “The Dancing Cavalier.”

Later, Lina learns that Kathy will be given on-screen credit as Lina's voice. She also learns that Don plans to marry Kathy. Lina responds by publishing an interview in which she claims that R.F. (the director) believes she is a major star. Lina plays hardball when R.F. confronts her. She threatens to sue R.F. if he does not remove Kathy Selden’s film credit.

Also, she wants Kathy to dub her voice forever, effectively ruining Kathy's showbiz career. She also wants Kathy to dub her voice permanently, ending Kathy's showbiz career.
