Light of wavelength 6000 Armstrong in air enters a medium of refractive index of 1.5 . What are the wavelength and frequency of light in that medium?
Can you please tell me that why I should take
v=3*10(raised to 8)/6000 Armstrong
Instead I can take v=3*10(raised to 8)/4000 Armstrong , because wavelength of light in that medium is 4000 Armstrong.
Spaceflight that landed Neil Armstrong to the moon is ____________.
calculate the mass of photon with wavelength=3.6 armstrong
