Question

State the names of radiations in the electromagnetic spectrum along with their wavelength ranges.

Answer 1

• Gamma (γ) rays: Below 0.1 Å (or less than 10⁻¹¹ m)
• X-rays: 0.1 Å to 100 Å (or 10⁻¹¹ m to 10⁻⁸ m)
• Ultraviolet (UV) rays: 100 Å to 4000 Å (or 10⁻⁸ m to 4 × 10⁻⁷ m)
• Visible light: 4000 Å to 8000 Å (or 4 × 10⁻⁷ m to 8 × 10⁻⁷ m)
• Infrared (IR) rays: 8000 Å to 10⁷ Å (or 8 × 10⁻⁷ m to 10⁻³ m)
• Microwaves: 10⁻³ m to 0.1 m
• Radio waves: Above 0.1 m
