Question

If the velocity of hydrogen molecule is 5 x 104 cm sec ), then its de Broglie wavelength is (1) 2 A (2) 4 A (3) 8 A (4) 100 A ​

Answer 1

Answer:

If the velocity of hydrogen molecule is 5 xx 10^4 cm sec^-1, then its de-Broglie wavelength is. =4×10-8cm=4Å.

Answer 2

Answer:

If the velocity of hydrogen molecule is 5 xx 10^4 cm sec^-1, then its de-Broglie wavelength is. =4×10-8cm=4Å

Explanation:

Correct Answer Is 4A
