At dawn and dusk, large amount of blue and violet light(shorter wavelength) has been scattered so, the light that is recieved by an observer is mostly of a longer wavelength and therefore appears to be red.
A negative of a vector represents the direction opposite to the reference direction. It means that the magnitude of two vectors are same but they are opposite in direction.
For example, if A and B are two vectors that have equal magnitude but opposite in direction, then vector A is negative of vector B.
तपाईंको जीवनमा सामाजिक अधययनले के कसता सकारातमक परभाव परेका छन , बुँदागत रुपमा लेखनुहोस I
सामाजिक अधययनले मेरो जीवनका पारेका सकारातमक अधययन निमनाअनुसार बुँदागत रुपमा परसतुत गरेको छु :
1. मैले संविधान वयवसथा गरेको हक, अधिकार, करतवय, दायितव आदि बारे बुझन पाएको छु I
2. मैले करतवयपरायणताको भाव बोध गरेको छु I
3. समाजका रीतिरिवाज, संसकार, परमपरा आदिको अधययनबाट फरक परिवेशमा समेत समावेशन हुन सकने सिपको विकास गरेको छु I
4. राषटरिय समपदाको संरकषण र देशको पृषठभूमिपरति पुरखाले...
Yes, a vector which has zero magnitude is also a vector in case of two vectors travelling in opposite directions with equal magnitudes. At this case, the resultant vector has zero magnitude but it is still a vector. We call it a null vector.
