When you move an object closer to the light source, the shadow it casts becomes smaller and more sharply defined. This is because the light source rays are more concentrated on the object, resulting in a more defined shadow with less diffused edges.
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
Doppler effect refers to the change in wavelength that occurs when an object moves toward or away from a source.
When the source of a sound is moving toward you, the sound waves emitted by the source are compressed, resulting in a higher frequency of the sound you hear. This phenomenon is known as the Doppler effect and is commonly experienced with sirens from emergency vehicles approaching you.
If a source is moving toward you at a high rate of speed, you would perceive an increase in its frequency, resulting in a higher pitch (Doppler effect). This is commonly experienced with emergency vehicles approaching with sirens on.

In this Thread, we will become familiar with the orientation of shadows, their size in relation to the object casting them, and how the alignment of the Sun, the object, and the shadow tells us much about how shadows work. The National Science Education Standards stress that geometry and light should be integrated into curricula as tools for learning about three dimensional objects. Vocabulary words which can be used to help talk about our experiences are alignment, casting, angle, and light source. The height of a tilted light source (in other words, the angle between the light source and the ground) and the size of the object it is illuminating determine the length of the shadow that the object casts. The object blocks the light coming from the source so that nothing behind the object gets any direct light. The length of the shadow is a result of how high above or below the top of the object the light source is. Imagine if the light source were directly above the top of the object. Would there be a shadow? No, not one that would be visible around the object. Twist the light source a little down from the top, and a shadow appears behind the object, but is very short. This is because as the light source moves down, the shadow is being created by the small area of the object blocking the light. Imagine straight lines coming down from the light and hitting the object. The higher the light, the less light lines get blocked by the object and hence the less shadow. Thus, the lower the light source is aimed at the object, the more the object blocks the lines, or rays, of light. The key to understanding shadows is to realize that the light source and object must be lined up in order to make a shadow appear. In fact, if the object is placed anywhere along that line, it will produce a shadow of the same length behind the object. It is only when you change the orientation of the light source that the shadow changes. That makes sense in one order: light hits an object and casts a shadow. But experiencing the connection of these fundamentals in a different arrangement is good for rooting our experiences more firmly. In other words, trying to predict where to place an object to cast a shadow at a specific location: essentially trying to locate the path of the light. We've made a brief page about solar eclipses. Solar eclipses are excellent examples of light and shadow. By JASON

As you walk toward the sun, your shadow will appear to get shorter and eventually disappear as you get closer to the light source. This is because the angle of the sun's rays hitting you changes, causing your shadow to diminish in size.
If the source of a sound is moving towards you, then the pitch of the soundyou hear is higher than the pitch of sound that the source is actually emitting.The rate of speed doesn't matter.BTW ... this also happens if you are moving toward the source.

The object pronoun is you, functioning as the object of the preposition 'toward'.
I'm assuming you are talking about the convergence reflex. If you are, they shifted toward the center of the object to focus and eventually see it.
