PPT-So is Light a Wave?

Rubbish light is made of particles If light diffracts and interferes then it must be a wave Newton Young Wave particle duality web link If light is a wave interference effects will be seen where one part of wavefront can interact with another part . Wave Pink, Wave Purple and Wave Lavender, the first flowers will appear closer to the center of the pot. 6-In. (15-Cm) Pots Apply a B-Nine spray at 2,500 to 5,000 ppm 7 to 10 days after transplanting. John Raynor – Business Research Services. High Point Public Library. Mark Sanders – Head of Reference.

Chandigarh. Interference. The term interference refers to phenomenon involving superposition of waves leading to a modification of their intensity in the region of superposition.. What is light? Particle, wave, etc.. How is light created?. How fast does it travel? (infinite vs. finite speed). Intromission vs. Emission & speed of light. Empedocles (~450 BC) argued that light was something in motion and took time to travel. Argued light was emitted by our eyes..
