Laser light exhibits much stronger interference effects than light from a flashlight. This is because:
laser light has a much shorter wavelength than light from a flashlight.
laser light is both coherent and monochromatic.
laser light carries much more energy than light from a flashlight.
laser light travels as waves while light from a flashlight travels as particles.

Consider each of the electric- and magnetic-field orientations given next. in each case, what is the direction of propagation of the wave? a)\vec ein the +xdirection,\vec bin the +ydirection. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction b)\vec ein the -y direction,\vec bin the +x choose+ x direction- x direction+ y direction- y direction+ z direction- z direction c)\vec ein the +z direction,\vec bin the -x direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction d)\vec ein the +y direction,\vec bin the -z direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction
