young double slit

What is meant by monochromatic light?

• A light source with one wavelength only
• A light source with one speed only
• A light source with only white light
• A light source that is coherent

When two waves combine to form a new wave with a larger amplitude, it is called 

• Diffraction
• Destructive Interference
• Resonance
• Constructive Interference

When two waves combine to form a new wave with a smaller amplitude, it is called 

• Refraction
• Constructive Interference
• Resonance
• Destructive Interference
