Coherence

Coherence is the connection between

• Phase

• Time

• Velocity

• Both a & b

The average time during which the phase of the wave train can be finite is called

• Coherence length

• Coherence time

• Coherent amplitude

• All of the above

Temporal coherence is related to the

• Bandwidth of the source

• Length of the source

• Finite size of the source

• Depend upon size of wave packet

Temperal coherence is also called as

• Longitudinal coherence

• Spatial coherence

• Lateral cohernce

• None of the above

Lateral cohernce is also known as

• Temporal coherence

• Spatial coherence

• Both a and b

• All of the above
