Name the electromagnetic radiations and write their frequency range:
(a) Used to take the photograph of the bones
(b) Produced by hot bodies
(c) Used in television communication systems
Show Hint
Different regions of the electromagnetic spectrum serve distinct practical purposes:
- X-rays: Imaging dense structures like bones.
- Infrared: Heat detection and remote controls.
- Radio waves: Communication over long distances.
(a) X-rays
Frequency range: \( 3 \times 10^{16} \text{ Hz to } 3 \times 10^{19} \text{ Hz} \)
Utilized in medical imaging for bone photography owing to their penetrating capability.
\medskip
(b) Infrared rays
Frequency range: \( 3 \times 10^{11} \text{ Hz to } 4.3 \times 10^{14} \text{ Hz} \)
Infrared radiation originates from heated objects and is linked to heat emission.
\medskip
(c) Radio waves
Frequency range: \( 3 \times 10^{6} \text{ Hz to } 3 \times 10^{8} \text{ Hz} \)
These are employed in television and radio communication networks due to their extensive reach and signal-carrying capacity.
