Calculate the diffraction limit of a telescope that is using a green filter of 556nm and has a diameter of 10 meters.

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f
