00:01 Hi in this question the wavelength of the radiation is given 5 to 2 nanometer and we have to convert this wavelength into meter so lambda is equal to here 5 2 nanometer and we know one nanometer is equal to 10 rest of power minus 9 meter so it can be written as 522 into 10 rest to the power minus 9 meter or we can say 5 .2 2 2 into 10.
00:31 10 to power minus 7 meter.
00:35 Now we have to convert this wavelength again into centimeter.
00:41 So 522 nanometer will equal to the here we can see 5 .2 to 10 to power minus 7 meter.
00:51 And 1 meter is equal to 100 centimeter.
00:55 So on solving this we will get 5 .22 into 10 to power minus 5 .5 nanometer.
01:04 Now we have to find the frequency for this wavelength 522 nanometer.
01:13 We know frequency is equal to c upon lambda and c is speed of light that is 3 into 10 power 8 meter per second and radiation in meter is 5 .22 into 10 s to power minus 7 meter...
