Which consequence results when high coherence laser light reflects off a rough surface?

💡 Explanation

A speckle pattern emerges because random variations cause constructive and destructive *interference*. High coherence amplifies the effect; therefore a speckle pattern of higher contrast appears, rather than a weaker pattern of lower contrast when lower coherence is used.
