X-Rays starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in X-Rays.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A hospital technician increases the voltage applied to an X-ray tube. What effect does this have on the X-ray spectrum produced?
Calculate the minimum wavelength of X-rays produced when electrons are accelerated through a potential difference of 50 kV. (Use h = 6.63 × 10-34 J·s, c = 3.00 × 108 m/s, e = 1.60 × 10-19 C)
Describe the difference between hard X-rays and soft X-rays.
Explain why X-rays are dangerous to living tissues.
Explain why X-rays are not deflected by electric or magnetic fields.
If the accelerating voltage in an X-ray tube is increased, what happens to the minimum wavelength of the emitted X-rays?
If the intensity of X-rays is reduced to half after passing through 2 cm of a material, what is the linear absorption coefficient μ? (Use I = I0e-μx)
Name the two main types of X-rays produced in an X-ray tube.
State Bragg's law for X-ray diffraction.
State one medical application of X-rays.
The intensity of X-rays passing through a material decreases exponentially with thickness. This is described by the equation I = I0e-μx. What does μ represent?
What is the main difference between X-rays and gamma rays?
Who discovered X-rays?
