Explanation:
Answer:
M1 Vx1 + M2 Vx2 + M3 Vx3 = 0 conservation of momentum in x direction
Vx3 = -(M1 Vx1 + M2 Vx2 ) / M3
Vx3 = - 320 * 2 / 100 = -6.4 m/s M2 has no x-component of momentum
Likewise:
Vy3 = -(M1 Vy1 + M2 Vy2 ) / M3
Vy3 = - 355 * 1.5 / 100 = -5.33 m/s
tan theta = -5.33 / -6.4 = .833 where theta is in the third quadrant and measured from the negative x-axis
theta = 39.8 deg
180 + 39.8 = 219.8 from the positive x-axis
First, let's calculate the frequency of this radiation, which is given by:
where c is the speed of light and
is the photon wavelength. For this radiation, photons have wavelength of
Therefore their frequency is
The energy of a photon with frequency f is given by
where h is the Planck constant. By using the frequency we found before, we find the energy of a single photon of this radiation:
Electromagnetic spectrum is a bunch of electromagnetic waves arranged according to their wavelength, from highest wavelength to the lowest wavelength
the highest wavelength will have the lowest energy value for eg micro wave
the lowest wavelength will have the highest energy value for eg cosmic waves
the order is
microwave,radiowave, infrared,red, orange, yellow,green,blue,indigo,violet, ultraviolet, Gamma rays and cosmic rays
