Concepts covered
Wave motion
Way of transporting energy from part of space to the other without any bulk motion of material together with it is wave motion. Sound is transmitted in air in this manner.
Waves that require a medium to travel are called mechanical waves and those which do not require a medium are called nonmechanical waves.
Travelling wave or progressive wave

General Theory of Relativity in Hindi
जनरल थ्योरी ऑफ रिलेटिविटी - अल्बर्ट आइन्स्टीन (Albert Einstein)
कल्पना कीजिए एक बिन्दु में विस्फोट होता है और वह कई भागों में बंट जाता है और भाग एक दूसरे से दूर जाने लगेंगे। और इसके लिये ये जगह को भी खुद से पैदा करेंगे। सभी भाग विस्फोट हुए बिन्दु से बाहर की ओर सीढ़ी रेखा में चलते जायेंगे। किन्तु अगर ये भाग एक दूसरे को परस्पर किसी कमजोर बल द्वारा आकर्षित करें ? तो इनकी गति सीढ़ी रेखा में नहीं रह जायेगी। अगर इन बिन्दुओं के समूह को आकाश माना जाये तो यह आकाश सीधा न होकर वक्र (curve) होगा

कल्पना कीजिए एक बिन्दु में विस्फोट होता है और वह कई भागों में बंट जाता है और भाग एक दूसरे से दूर जाने लगेंगे। और इसके लिये ये जगह को भी खुद से पैदा करेंगे। सभी भाग विस्फोट हुए बिन्दु से बाहर की ओर सीढ़ी रेखा में चलते जायेंगे। किन्तु अगर ये भाग एक दूसरे को परस्पर किसी कमजोर बल द्वारा आकर्षित करें ? तो इनकी गति सीढ़ी रेखा में नहीं रह जायेगी। अगर इन बिन्दुओं के समूह को आकाश माना जाये तो यह आकाश सीधा न होकर वक्र (curve) होगा
