खालीलपैकी योग्य वाक्यांची निवड करा. / Choose correct statements from the following :
(a)ध्वनिहरी वायू पदार्थापेक्षा स्थायू पदार्थातून वेगाने जातात. / Sound waves travel faster in solids than in gases.
(b)ध्वनिहरी निर्वात पोकळीतून सर्वात जलद गतीने जातात. / Sound waves travel fastest through vacuum
(c)ध्वनिहरी अनुलंभ लहरी आहेत. / Sound waves are longitudinal waves
(d)ध्वनिहरी द्रव पदार्थापेक्षा वायू पदार्थातून कमी वेगाने जातात. / Sound waves travel slower in gases than in liquids.
Sound waves travel fastest in solids (a), are longitudinal waves (c), and travel slower in gases than in liquids (d). Statement (b) is false because sound cannot travel through a vacuum at all.
_____________ च्यासाहाय्याने दूरचित्रवाणीचे कार्यक्रम सर्व जगामध्ये पाठविणे शक्य आहे. TV programmes can be transmitted all over the world, with the help of ____________ .
(a)भूस्थिर उपग्रह / geostationary satellites
(b)अंतरंग तरंग प्रसारण / space wave propagation
(c)भूतरंग प्रसारण / ground wave propagation
(d)अणू तरंग / longitudinal waves
Geostationary satellites revolve at the same speed as the Earth and cover large areas, making them ideal for telecommunication and transmitting TV programs worldwide. Ground and space wave propagations have distance limitations.
