1. Which radiation has the shortest
wavelength, greatest energy and highest frequency
The radiations
with the shortest wavelength, greatest energy is the gamma ray
2. yellow light can have a wavelength of 579
nm. The energy of a photon of this light is
If the
wavelength is given as 579*10-9 , the
energy can be calculated as follows,
E=hf=hc/λ
Where c
=3*108m/s, h = 6.62607004 × 10-34 m2 kg / s, from this
We can calculates the energy of the yellow light as follows
E
=hc/ λ =3.1*10-19newton.
3. what has the longest wavelength in the
electromagnetic spectrum?
The waves
with the longest wavelength in the spectrum is the radio waves
