27
Q

spectrometer

A

an optical device for measuring wavelengths deviation of refracted rays and angles between faces of a prism

28
Q

wave length

A

the distance, measured in the direction of propagation of a wave between two successive points in the wave that are characterized by the same phase of oscillation.

29
Q

Frequency

A

the state or fact of being frequent so a frequent occurrence

32
Q

galaxy

A

a large system of stars held together by mutual gravitation and isolated from similar systems by vast regions of space.

33
Q

redshift

A

a shift toward longer wavelengths of the spectral lines emitted by a celestial object that is caused by the object moving away from the earth.

34
Q

blue shift

A

a shift toward shorter wavelengths of the spectral lines of a celestial object caused by the motion of the object toward the observer.

35
Q

doppler affect

A

the shift in frequency of acoustic or electromagnetic radiation emitted by a source moving relative to an observer as perceived by the observer: the shift is to higher frequencies when the source approaches and to lower frequencies when it recedes.
