How do photons travel in waves?

In energy wave theory, a photon is generated by the vibration of particles, traveling perpendicular to the direction of vibration. These are the two components of the wave (longitudinal and transverse). Longitudinal waves constantly flow from particles, causing an electric field even when a particle is not in motion.

Does a single photon travel as a wave?

But we discover that as soon as the photon travels out into free space, the single photon spreads out into a wave that has a non-zero width and acts just like a coherent beam containing trillions of photons.

How does light travel in a straight line if it is a wave?

Light travels as waves. Light waves travel in straight lines. You can detect them with your eyes, and also with instruments such as cameras. They are reflected by mirrors and change direction when they travel from the air into glass or water.

Do all waves travel in a straight line?

Waves travel in straight lines. A wave carries energy from a source to a point some distance away. The reflected wave moves away from the barrier at an angle that is equal to the angle with which the incoming wave moved towards the barrier. When a wave is slowed down, it refracts—that is, changes direction.

Why do particles travel in straight lines?

Particles have momentum and positions. Particles will move in straight lines until something changes their direction. Many physical interactions can be described simply as particles bouncing off of one another. On the other hand, waves are almost completely different.

Which of the following are characteristic of photon has?

Photons have no mass but they have energy. E=hv where h is the planks constant. The energy of each photon is inversely proportional to the wavelength of the associated EM wave. E=hv=hλc​

Why does light not always travel in a straight line?

As far as light is concerned it travels in a straight line from point A to point B. However, for a distant observer the trajectory may be a bit curved. The reason is that the geometry of space is a bit warped near a massive gravitational source like a black hole or even the sun.

Which waves are Travelled in a straight path?

As the wavelength of light is below one micrometer, light behaves like straight rays in daily live. Wave effects are scarce, and usually require sophisticated equipment for demonstration. Light travels in straight lines, as electromagnetic waves. Light travels in straight lines, as electromagnetic waves.
