Kinetic energy of proton is the same as that of an `alpha`-particle. What is the ratio of their respective de Brogile wavelengths?

An electron and a proton have same kinetic energy Ratio of their respective de-Broglie wavelength is about

An alpha -particle and a proton are accelerated in such a way that they get the same kinetic energy. What is the ratio of their de Broglie wavelengths?

A deuteron and an alpha - partical have same kinetic energy. Find the ratio of their de-Broglie wavelengths.

An alpha particle and a proton are accelerated in such a way that they get the same kinetic energy. What is the ratio of their de- broglie wavelengths ?

What is the ratio of mass of an alpha -alpha particle and a proton ?

A proton, a neutron, an electron and an alpha -particle have same energy. Then their de-Broglie wavelengths compare as

An alpha -particle and a proton are fired through the same magnetic field which is perpendicular to their velocity vectors. The alpha -partcles and the proton move such that radius of curvature of their paths is same. Find the ratio of their de Broglie wavelengths.

An alpha particle and a proton have their masses in the ratio 4:1 and charges in the ratio 2: 1. Find ratio of their de-Broglie wavelengths when both move with equal velocities. In Q-20, find ratio of de-Broglie wavelengths, when both have equal kinetic energy.
