Answer:
a) red wave hs a longer wavelength than the green wave
b)f = 1.875 10¹¹ Hz
,  f_green = 5.45 10¹⁴Hz
c)   E = 1.24 10⁻²² J
, E_green = 3.6 10⁻¹⁹ J
d) The red wave is in the infrared range, heat waves
The green wave is in the visible wavelength
Explanation:
a) The green wave are on the left in the electromagnetic spectrum so the red wave has a longer wavelength than the green wave
The green wavelength is in the range of 550 10⁻⁹ m
The speed of the wave is
             c = λ f
             f = c /λ
b) The frequency of the red wave is
             f = 3 10⁸ / 1.6 10⁻³
             f = 1.875 10¹¹ Hz
For the green wave
            f_green = 3 10⁸/550 10⁻⁹
            f_green = 5.45 10¹⁴Hz
c) The photon energy is given by the Planck equation
              E = h f
              E = 6.63 10⁻³⁴ 1.875 10¹¹
              E = 1.24 10⁻²² J
For the green wave
               E_green = 6.63 10⁻³⁴ 5.45 10¹⁴
               E_green = 3.6 10⁻¹⁹ J
d) The speed of electromagnetic waves is constant and has a value of 3 108 m / s
e)  
The red wave is in the infrared range, heat waves
The green wave is in the visible wavelength
