Optics T/F questions (7):

1, A wave propagating in the positive direction would be a function / (s-pt) True False 2. A spherical wave propagating along the radial component towards the origin would be a function True Faise 3. The phase of the plane wave (r,t) does not have a constant phase at every position and time respectively True ) False 4. A spherical wavefront of harmonic wave has a composition of angular frequencies a) True b) False 5. In transversal waves E and i are parallel to each other but k may be parallal to aither B o B a) True ) False

Explanation / Answer

True. Gamma rays have shorter wavelength than X rays. Since energy is inversly proportional to wavelength, gamma rays have more energy than X rays.
