Light with wavelength 633 nm is incident on a 3.00-μm-wide slit. part afind the angular width of the central peak in the diffraction pattern, taken as the angular separation between the first minima.

The angular width of the central peak is 24.2 degrees

Explanation:

The equation that describes the single-slit diffraction phenomenon is:

(1)

with a the width of the slit, the angular position of the minimum regarding the center of the screen where light is projected, m the order of the minimum and the wavelength. Solving (1) for with m=1 that is the first minimum:

See the figure below that the central peak is symmetric regarding the center of the screen, which implies that the angular width of the central peak is

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
