Light from a helium-neon laser

Reference no: EM13674666

What is the spacing (in mm) among the slits?

Light from a helium-neon laser (? = 633 nm) is utilized to illuminate two narrow slits. The interference pattern is observed on a screen3.3m behind the slits. Eleven bright fringes are seen, spanning a distance of 51mm

The phase angle of the resultant wave : These two waves travel along the same string: y1 = (4.17 mm) sin (2.24?x - 300?t), y2 = (5.96 mm) sin(2.24?x - 300?t + 0.727?rad). What are (a) the amplitude and (b) the phase angle (relative to wave 1) of the resultant wave?

Different ball was dropped and the final speed was gauged : An ant travels in a perfectly straight line in the –x direction some distance. It turns, and then travels some new displacement, 30.0 degrees above the +x axis, again, in a straight line, for some distance. The final leg of its little ant journey is ..

The attenuation of ultrasound in tissue : The attenuation (intensity loss) of ultrasound in tissue is approximately 0.3 dB per MHz per cm of depth. (E.g., a 3 MHz signal travelling during 2 cm of tissue has its initial intensity reduced by 0.3×3×2 = ?1.8 dB.)
