If wavelength is equal to the distance travelled by the electron in one second then

how fast is an electron moving if it has a wavelength equal to the distance travelled in one second ?

how fast is an elecreon moving if it has a wavelength equal to the distance travelled in one second ?

If the wavelength of the electron is numerically equal to the distance travelled by it in one second, then

If a freely falling body travels in the last second, a distance equal to the distance travelled by it in the first three second, the time of the travel is

If a freely falling body travels in the last second a distane equal to the distance travelled by it in the frist three seconds,the time of travel is :

If a freely falling particle in thelast second travels a distance equal to the distance traveled in the first three consecutive seconds the time of its travel is
