& Answers .
Question 1 (MC)
Who discovered X-rays on November 8, 1895?
A) Antoine Henri Becquerel
B) Marie Curie
C) Wilhelm Conrad Roentgen
D) Thomas Edison
Answer: C) Wilhelm Conrad Roentgen
Rationale: Wilhelm Conrad Roentgen discovered X-rays while
experimenting with cathode ray tubes. He noticed a fluorescent
,Page 2 of 188
screen glowing in his laboratory even though the tube was
covered. He named the unknown radiation “X-rays” (X for
unknown). This discovery earned him the first Nobel Prize in
Physics in 1901.
Question 2 (MC)
What did Roentgen use as the detector in his initial X-ray
experiments?
A) Photographic film
B) Barium platinocyanide-coated screen
C) Ionization chamber
D) Geiger counter
Answer: B) Barium platinocyanide-coated screen
,Page 3 of 188
Rationale: Roentgen observed fluorescence on a barium
platinocyanide screen. He later placed his wife’s hand on a
photographic plate, producing the first radiograph of a human
body part (the hand). This discovery marked the beginning of
diagnostic radiography.
Question 3 (T/F)
The first Nobel Prize in Physics was awarded to Marie Curie for
her work on radioactivity.
Answer: False
Rationale: The first Nobel Prize in Physics (1901) was awarded
to Wilhelm Conrad Roentgen for the discovery of X-rays. Marie
Curie won Nobel Prizes in Physics (1903) and Chemistry (1911)
for her work on radioactivity.

Question 4 (FIB)
The unit of exposure in air for X-radiation is the __________.
Answer: roentgen (R)
Rationale: The roentgen (R) is a legacy unit of exposure that
measures the ionization produced in air by X- or gamma
radiation. It is defined as 2.58 × 10⁻⁴ C/kg. Modern SI units use
coulombs per kilogram (C/kg), but the roentgen remains
important for understanding historical literature and equipment.
Question 5 (MC)
Which of the following is a property of X-rays?
A) They can be focused by lenses.
B) They travel at the speed of sound.
