Speed of light

[Sir Kushagra Kirtiman]

Horizontal Speed is equal to speed of source agree or not

[Klaynos]

The question doesn't really make sense.

[jduff]

Horizontal Speed is equal to speed of source agree or not

What exactly do you mean by horizontal speed? Relative to what? Would it really be horizontal?? I agree with the poster above. The question does not make any sense! Makes me think of apples!

[Strange]

The speed of light (in any direction) is always the same, independent of source or observer.
