question 38

Multiple Choice

In the Compton scattering experiment shown in the figure,a monochromatic beam of X-rays strikes a target containing free electrons.Scattered X-rays are detected with a wavelength of 2.50 × 10^-¹² m at an angle of 45° away from the original beam direction.What is the wavelength of the incident monochromatic X-rays? Note: The mass of an electron is 9.11 × 10^-³¹ kg.

Lateral Separation

The physical or conceptual distance between objects or entities on a horizontal plane.

Left Eye

Refers to the eye on the left side of the body, which, along with the right eye, provides part of the visual field and depth perception.

Perceptual Constancy
