A certain rifle bullet has a mass of 9.09 g. Calculate the de Broglie wavelength of the bullet traveling at 1937 miles per hour. Consult the table of physical constants as needed.

Answer 1

> The de Broglie warekasth, a mv m= mass of the particle & Sintoina velocity of the partice. . Here, V = 1937 miles/hour = 19374 1609.34 m. ry 36005 S = 8.65 x102 m.st. 1 .22 6.626 X 1034 Jis- (9.09x103) Kg x 8:6 5x10² m/s. = 8.426 x 1035 m J = kg m / sra Ta ko. mis 7 x 8 = 8.42 x 10-25 ѕ хуй So, the de Broglie wavelength of the bullet io- 8.424 1025 Å.
