Question

Which sequence gives electromagnetic waves in order of increasing wavelength?

विकल्प

• Gamma rays → X-rays → Ultraviolet rays → Visible light → Infrared radiation → Microwaves → Radio waves

• Radio waves → Microwaves → Infrared radiation → Visible light → Ultraviolet rays → X-rays → Gamma rays

• Gamma rays → Ultraviolet rays → X-rays → Visible light → Microwaves → Infrared radiation → Radio waves

• X-rays → Gamma rays → Ultraviolet rays → Visible light → Infrared radiation → Radio waves → Microwaves

Answer 1

Increasing wavelength runs from gamma rays through X-rays, ultraviolet rays, visible light, infrared radiation, and microwaves to radio waves. Frequency decreases along this sequence.
