Monochromatic light with a wavelength of 6.4 e -7 meter passes through two narrow slits, producing an interference pattern on a screen 4.0 meters away. the first order bright band lines are 2.0 e -2 meters away from the central bright maxima. what is the distance between the slits?

1.3 e -4 m

8.0 e -6 m

3.2 e -9 m

7.8 e3 m

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
