Photons travel outward from a light source in?
the photons travel outward from a light source in all directions.
What causes shock waves?
A shock wave is generally thought of as a compression wave that radiates from a mechanical event, like an explosion. Same thing with earthquakes. There is a compression wave in all these events. We can see a compression wave originate from something breaking the sound barrier, and that's another example. Something moving faster than sound generates the shock wave on a continuous basis, and we hear the boom! as the wave reaches us. The same thing applies in sonar when the transmitter emits a "ping" into the water. The transducer vibrates, and a compression wave is generated. Where a source of mechanical energy causes movement, a compression wave can originate and radiate. It could be argued that compression waves originate from a source of sound. That's because sound is a mechanical wave, as it is mechanical energy. Certainly it generally isn't thought of as having the power of an explosion, though. In addition to the compression waves of sound, there are the "opposite" waves. These are areas where the air is rarefied or "uncompressed" between the areas where the compression waves are traveling. A shock wave is usually the term we apply to the leading edge of a compression wave from some mechanical event. It is carrying mechanical energy outward from the cause.
When does the pitch of sound change?
When the frequency of the vibrations that produce the sound change. Higher frequencies -> higher pitch. OR if the source of the sound is moving towards or away from you -> Doppler effect.
Do sound waves travel either inward or outward from their source?
Sound waves consist of both compression and rarefaction. The compression is caused when something pushes air away, and it bunches up, causing a pressure increase. Rarefaction is the reverse; when you pull away, you create a low pressure area and pull the air with it. However, the overall energy expenditure moves outwards, as each successive volume of air is affected by the one before it, which was affected by the one before that, all the way back to the source.
What can scientist measure when light rays are emmitted by a moving source?
Scientist measure when light rays are emitted by a moving source the speed of light. Depending on the moving force they can also measure bending light.
Photons travel outward from a light source in?
the photons travel outward from a light source in all directions.
What direcstion does light travel?
Outward from the source.
What moves outward from the source of an earthquake?
seismic waves

Where do you get the exact source code in C that implements lossless compression algorithm?
The source code, in C, will depend on what type of lossless compression algorithm will be used. A source code should be available from various computer scientists in your area.

What is non luminous source?
It is a source which does not produce light.
What determines if sound is loud or soft?
The determining factor as to the softness or loudness of a sound is the amplitude of the sound wave. We know that sound is mechanical energy, and a source of sound will put mechanical energy into the medium through which it is going to travel. Let's look at the wave. The mechanical wave has a compression phase and a rarefaction phase. In compression, the source compresses the medium to impart energy. In the rarefaction phase, the source will act to decompress the medium. The sound will propagate outward in a series of compression and decompression phases. The difference between a loud and a softer sound is the degree to which a medium is compressed and rarefied during the process by which the sound energy is put into the medium. Fortunately there is a question (and an answer) that goes into this in a bit of detail. It is linked in the Related questions section.

Is moving water an energy source?
Yes. It is source of mechanical energy.
What are magnetic cars?
Magnetic air cars uses air compression as the source for propusion. It is "magnetic" in the sense that a magnetic motor is used for the air compression.
