Structures on a bird feather act like a diffraction grating having 8000 8000 lines per centimeter. what is the angle of the first-order maximum for 452 nm 452 nm light shone through a feather?

Angle of first order maximum,

Explanation:

Given that,

Wavelength of the light,

Number of lines, N = 8000 per cm

The relation between the number of lines and the slit width is given by :

The equation of grating is given by :

n = 1

So, the angle of the first-order maximum is 21.19 degrees. Hence, this is the required solution.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

total distance/total time

(85 + 82)/(5+3)
