Question

Hard X-rays for the study of fractures in bones should have a minimum wavelength of 10⁻¹¹ m. What is the accelerating voltage for electrons in X-ray machine?​

Answer 1

✯ Given,

➵ Minimum Wavelength = 10⁻¹¹ m

━━━━━━━━━━

✯ We Know that,

➸ eV0 = hvmax or eVo = hc/λmin

➵ Vo = hc/eλmin

➵ Vo = 12400 × 10−10/10⁻¹¹

➵ Vo = 124kv

━━━━━━━━━━

➲ The accelerating voltage for electrons in X-ray machine is 124kv.

Answer 2

Answer:

Explanation:

Minimum Wavelength = 10⁻¹¹ m (Given)

eVo = hc/λmin

Vo = hc/eλmin

Vo = 12400×10−10/10⁻¹¹

Vo = 124kv

Therefore, the accelerating voltage for electrons in X-ray machine should be less than OR EQUAL TO 124kv
