Question

what is the wavelength of car with a mass of 1.3*1000kg moving at a speed of 10m/s?

Answer 1

Given:

Mass of a car (m) = 1.3×1000kg

Speed of a car (v) = 10m/s

To find the wavelength (λ) of car

Solution:

Use de Broglie's equation

λ = h/m×v where h is Planck's constant that equals to 6.6262 x 10^-34 Js

λ =  6.6262 x 10^-34/(1.3×1000×10)

λ = 5.09×10^-35m

Hence, the wavelength of the car is 5.09×10^-35m.

Answer 2

Answer: Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.

Explanation:

to answer the question lets first write

Given:

Mass of a car (m) = 1.3×1000kg

Speed of a car (v) = 10m/s

To find the wavelength (λ) of car

answer

Using de Broglie's equation

λ = h/m×v

where h is Planck's constant that equals to 6.6262 x 10^-34 Js

λ =  6.6262 x 10^-34/(1.3×1000×10)

λ = 5.09×10^-35m

Hence, the wavelength of the car is 5.09×10^-35m.
