A technician wishes to determine the wavelength of the light in a laser beam. To do so, she directs the beam toward a partition
with two tiny slits separated by 0.175 mm. An interference pattern appears on a screen that lies 4.95 m from the slit pair. The technician's measurements show that two adjacent bright interference fringes lie 1.60 cm apart on the screen. What is the laser's wavelength (in nm)
Well it's <span>False. They have a definite volume, but not a definite shape. GASES have neither a definite shape nor definite volume! Hope I could help!</span>
