What is the de Broglie wavelength of a bullet of mass 0.030 kg traveling at 540 m/s? Planck's Constant is 6.63 × 10−34 J⋅s.

4.1 × 10−35 m
3.5 × 10−35 m
2.2 × 10−34 m
1.7 × 10−34 m

I believe the answer is 4.1 * 10^-35 m

Explanation:

I worked out the problem using the equation for this kind of wavelength.

Since I don't have the special keybind for it, ? will be the wavelength.

? = h/p

In this case, h = Planck's constant, which is 6.63 * 10^-34 J*s.

P = momentum, which is mass * velocity.

M (mass) = 0.030 kg.

V (velocity) = 540 m/s.

0.030 * 540 = 16.2.

P = 16.2

? = h/p

? = (6.63 * 10^-34) / 16.2.

? = 4.0925 * 10^-35.

? = 4.1 * 10^-35.

The wavelength is 4.1 * 10^-35 m.

i need the answer to this too but idk it ; -;

d is the correct answer
