• Can two laser sources be coherent sources?
Divya Garg
6 months ago
• A laser light is a coherent source. Two different laser light sources will be two different sources of light and they can produce interference pattern on a screen because each source emits coherently. When the phase difference between two independent sources stays constant due to coherence, interference can occur.

• Explain me power of lens
Divya Garg

• The power of a lens is its ability to bend light – the greater the power the greater the refraction of light. The +ve sign of the power indicates that the lens is a converging lens or convex lens, whereas the negative sign of the power indicates that the lens is concave or diverging lens. The S.I unit of the power is Dioptre or 1/metre. Power = 1/focal length (in m).
