What is the typical size range of nanoparticles?a) 1 to 100 millimetersb) 1 to 100 micrometersc) 1 to 100 nanometersd) 1 to 100 picometers

In part A of the experiment a hair is illuminated with a laser and a diffraction pattern is observed. The wavelength λ = 624 nm and the pattern is projected on to the wall a distance L = 2.3 m from the hair. The distance across the central maximum is measured to be 2y= 0.051 m.Calculate the width of the hair in µm (1x10-6m) to one decimal place. You do not need to specify the units.

Q6: Suppose your hair grows at the rate 1/32 in per day. What is the rate at which it grows in nanometers per second? [1 in = 2.54 cm, 1 d = 86 400 s, and 109 nm = 1 m] (a) 92.0 nm/s (b) 91.9 nm/s (c) 9.2 nm/s (d) 91.0 nm/s (e) 919.0 nm/s Q7: The JCR of a student hostel is 50.0 ft long and 26 ft wide and has 8.0-ft high ceilings. What is the volume of the interior of the room in cubic centimeters? [1 ft = 0.304 8 m]. (a) 2.94 × 103 cm3 (b) 3.17 × 103 cm3 (c) 2.94 × 108 cm3 (d) 2.9 × 108 cm3 (e) 2.98 × 108 cm3 4
