Monochromatic light of wavelength 574 nm is incident on a narrow slit. on a screen 2.38 m away, the distance between the second diffraction minimum and the central maximum is 1.82 cm. (a) calculate the angle of diffraction θ of the second minimum. (b) find the width of the slit.

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?

What equation is used to calculate the weight of an object on a plant ?

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
