1.	Frequency of a radiation having a wavelength of 1000Aº is....... plzzz answer this question it's urgent
Answer» ANSWER: FREQUENCY f=c/lambda c VELOCITY of light=3 ×10^8 m/sec lambda=1000A°=1000×10^-10 m=10^-7m Frequency , f=3×10^8 / 10^-7 =3×10^15 HZ

Frequency of a radiation having a wavelength of 1000Aº is....... plzzz answer this question it's urgent

Answer»

FREQUENCY f=c/lambda

c VELOCITY of light=3 ×10^8 m/sec

lambda=1000A°=1000×10^-10 m=10^-7m

Frequency , f=3×10^8 / 10^-7 =3×10^15 HZ
