A _________ is a disturbance that moves through a medium when the particles of the medium set neighbouring particles into motion.
______ एक विक्षाभ है जो किसी माध्यम में तब संचारित होता है जब माध्यम के कण पड़ोसी कणों को गति में लाते हैं।
Detailed Solution & Logic
wave / तरंग
Explanation / व्याख्या
A wave is a disturbance that travels through a medium when particles of the medium transfer energy by setting neighboring particles into motion.
तरंग (Wave) एक विक्षोभ (disturbance) है, जो किसी माध्यम में तब आगे बढ़ता है जब माध्यम के कण अपनी ऊर्जा पड़ोसी कणों को देकर उन्हें गति में लाते हैं।
A wave transfers energy, but not matter.
तरंग ऊर्जा का संचार करती है, लेकिन पदार्थ का नहीं।
Extra Facts / अतिरिक्त तथ्य
Two main types of waves:
तरंगों के दो मुख्य प्रकार होते हैं:
- Mechanical Waves / यांत्रिक तरंगें
Need a medium to travel.
इन्हें चलने के लिए माध्यम की आवश्यकता होती है।
Example: Sound waves / ध्वनि तरंगें - Electromagnetic Waves / विद्युतचुंबकीय तरंगें
Do not need a medium.
इन्हें माध्यम की आवश्यकता नहीं होती।
Example: Light waves / प्रकाश तरंगें
Important wave terms:
- Frequency (आवृत्ति) → Number of vibrations per second
- Amplitude (आयाम) → Maximum displacement from mean position
- Wavelength (तरंगदैर्ध्य) → Distance between two successive crests or troughs
Sound travels fastest in solids and slowest in gases.
ध्वनि ठोस में सबसे तेज़ और गैसों में सबसे धीमी चलती है।
Answer: Wave / तरंग
