Calculate the energy of a photon having a wavelength in thefollowing ranges.(a) microwave, with λ = 50.00 cmev(b) visible, with λ = 500 nmev(c) x-ray, with λ = 0.50 nmev

(a)

The energy of a photon is given by:

where

is the Planck constant

is the speed of light

is the wavelength

For the microwave photon,

So the energy is

And converting into electronvolts,

(b)

For the energy of the photon, we can use the same formula:

For the visible light photon,

So the energy is

And converting into electronvolts,

(c)

For the energy of the photon, we can use the same formula:

For the x-ray photon,

So the energy is

And converting into electronvolts,

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
