In a young's double-slit experiment, the slits are 0.03 cm apart and the screen is placed 1.54 m away. The distance between the central bright fringe and fourth bright fringe is 1 cm. Calculate the wavelength of light used. Describe Netwon's ring experiment and derive expression for wavelength of light. If light travels from one medium to another, its velocity changes. Is it due to the change in frequency or wavelength? Explain. A wire whose mass is 10-3 kg/m is stretched by a load of 4kg over the two bridges of a sonometer wire 1 m apart. It is struck at its middle point. What would be the wavelength and frequency of its fundamental vibration? A source of the sound of frequency 550 Hz emits waves of wavelength 60 cm in the air at 20° C. What would be the wavelength of sound from the source in the air at 0° C. A radio station broadcasts at 800 kHz. If the radio waves (em-waves) travel with a speed of 3x10^8 m/s, what will be the wavelength of the wave? PathshalaNepal.com is a Registered Company of E.

लोकसेवा आयोगले चैत्र महिनामा लिने परीक्षा स्थगित गरेको छ।बिहीबार बसेको आयोगको बैठकले चैत ८ गतेपछि संचालन हुने सबै लिखित परीक्षा स्थगित गरेको हो। चैत ८ गतेदेखि चैत मसान्तसम्मको लिखित परीक्षा स्थगित गरेको उपसचिव शर्माले जानकारी दिएका छन् । विज्ञप्ति जारी गर्दै लोक सेवा आयोगले सञ्चालन गर्ने निजामती सेवा, सुरक्षा निकाय र संगठित संस्था तर्फका लिखित परीक्षाका कार्यक्रम अर्को सूचना नभएसम्मका लागि स्थगित गरेको जनाएको छ। त्रिभुवन विश्वविद्यालयले पनि चैत महिनाभित्रमा सञ्चालन गरिने सम्पूर्ण परीक्षा स्थगित गरेको छ । क्याम्पमा कार्यरत प्राध्यापकलाई पनि चैत मसान्तसम्म विदा दिने निर्णय गरेको छ । यो विदा आगामी बर्षे तथा हिउँदे विदामा मिलान गरिने उनले जानकारी दिए । विश्वविद्यालय बन्द भएपछि करिब ५ लाख विद्यार्थी र ७ हजार प्राध्यापक घरमै बस्नेछन्। पाल्पाको लुम्बिनी मेडिकल कलेजले ज्वरो आएका बिरामीलाई एम्बुलेन्समै सोधपुछ गरी फर्काइदिएको छ । बगनासकाली गाउँपालिका २ पोखराथोकका २० वर्षीय दामोदर कुमाललाई कलेजले घरमै आइसोलेसनमा बस्न सुझाउँदै फर्कादिएको हो । ‘मलाई ज्वरो आएको छ, खोकी लागेको छ, […] The skull is made out of two arrangements of bones cranial and facial. Cranial bones are 8 in number, facial bones are 14. Thus, the skull is made of all-out 22 bones. The cranial bones […] PathshalaNepal.com is a Registered Company of E. Pathshala Pvt Ltd Nepal.
