Question

which best describes a difference between laser light and regular light? laser light is less concentrated. laser light has a beam that spreads out. laser light is made of one specific color. laser light pumps out light particles one at a time.

Explanation:

• Laser light is coherent (waves are in - phase), monochromatic (single - color), and highly directional. Regular light is incoherent (waves are out - of - phase), polychromatic (many colors), and spreads out.
• Option 1: Laser light is more concentrated, not less.
• Option 2: Laser light has a narrow, non - spreading beam. Regular light spreads out.
• Option 3: Laser light is monochromatic (one specific color), while regular light (like white light from a bulb) is a combination of many colors.
• Option 4: This is not a characteristic difference.

Answer:

Laser light is made of one specific color.
