No, the Doppler effect can occur for any relative motion between a source and an observer, not just motion along the line of sight. This includes motion perpendicular to the line of sight, as well as away from or towards the observer.
It is not Doppler frequency. It's Doppler effect. The APPARENT change in the frequency of the source as there is a relative motion between the source and the observer is defined as Doppler effect. The expression for frequency (apparent) is given fapparent = [(C - Vo + Vm)/(C-Vs+Vm)] x freal The condition to be kept in mind is that the source is on the left side and the observer on the right side along positive X axis. Vm - velocity of the medium and the medium is moving along positive X axis. Vo - the velocity of the observer Vs - the velocity of the source C - velocity of the wave either sound or light But in case of light Vm is not needed as the medium movement will not affect the velocity of the wave in any way.
Rectilinear motion is motion along a straight line, while linear motion is motion in a straight line in any direction. Rectilinear motion is restricted to motion along a single axis, while linear motion can occur along any direction in a straight line.
No, the motion of a body along a curved path is not translational, as translational motion refers to straight-line motion. The motion of a body along a curved path involves a combination of translational and rotational motion due to changes in direction.
The types of translational motion include rectilinear motion (motion along a straight line), curvilinear motion (motion along a curved path), and general plane motion (combination of translation and rotation).
Rectilinear motion is motion along a straight line, while circular motion involves moving along a circular path. One can be seen as a special case of the other - circular motion can be decomposed into both rectilinear motion along the tangent and angular motion around the center.
The Doppler shift only measures the component of motion directly towards or away from the observer. Motion across the celestial sphere does not impact the frequency of light perceived by the observer along the line of sight. This is because the Doppler effect is only sensitive to changes in the relative velocity between the source and observer along the line connecting them.

The method used to determine a star's speed of approach is called "radial velocity." This technique measures the star's motion towards or away from us along the line of sight by analyzing the Doppler shift in its spectral lines. The amount of shift in the spectral lines provides information about the star's speed and direction of motion relative to us.
There are a few different ones out there, but most of them work by the Doppler principle and on sound at ultrasonic frequencies. Doppler effect is the appearent shift in the frequency of a signal (wave) because of motion of the source or observer (or both) toward or away from each other. We've seen Doppler effect in action. Like with a train or race car. As the vehicle comes toward the observer, we hear a sound. As the vehicle zips by, the pitch or frequency of the sound drops. That's Doppler effect. By installing a small ultrasonic sound transmitter and receiver, an area of coverage is "painted" with the ultrasonic sound. Then the receiver along side it listens for an echo. If nothing in the room is moving toward or away from the source, all the returning signals will be the same as the ones that left the source. But if there is some relative motion, the detector "hears" the difference in the pitch of the sound (Doppler effect) and an alarm is triggered.
Rectilinear motion is motion along a straight line, while linear motion is motion in a straight line in any direction. Rectilinear motion is restricted to motion along a single axis, while linear motion can occur along any direction in a straight line.

It is the motion along a circular path.
The types of translational motion include rectilinear motion (motion along a straight line), curvilinear motion (motion along a curved path), and general plane motion (combination of translation and rotation).
Rectilinear motion is motion along a straight line, while circular motion involves moving along a circular path. One can be seen as a special case of the other - circular motion can be decomposed into both rectilinear motion along the tangent and angular motion around the center.
The motion along a straight line is known as rectilinear motion.
Gravity is completely responsible for planetary motion. The shape and size of each orbit, and the speed of the planet at every point in its orbit, taken along with the mass of the sun, are completely determined by the behavior of gravity.
Motion along a straight-line path is called rectilinear motion. In rectilinear motion, an object moves in a straight line with constant speed or acceleration. This type of motion is common in scenarios such as objects moving along a road or projectile motion.
