What is it increases intensity
How does distance affect x-ray beam intensity?
What is as distance increases, intensity decreases

What happens to x-ray beam intensity when exposure time is increased?
What is it produces a more intense x-ray beam
How can exposure time be adjusted to maintain image density?
What is by changing milliamperage
What happens to the intensity of the x-ray beam when the distance is doubled?
What is it becomes one quarter as intense
How does increasing kilovoltage affect the x-ray beam?
What is it increases the energy and shortens the wavelengths
What is the effect of a decrease in milliamperage on exposure time?
What is exposure time must increase?
Explain the relationship between milliamperage and x-ray beam intensity.
What is higher milliamperage increases intensity
How does exposure time influence the overall quality of an x-ray image?
What is longer exposure time can lead to better quality but risks overexposure
Name the three distances to consider in dental radiography.
What are target-surface, target-object, and target-receptor
What is the relationship between kilovoltage and image density?
What is higher kilovoltage increases density of the image
Describe how milliamperage affects the number of x-rays produced.
What is higher milliamperage produces more x-rays?
What is the importance of exposure time in producing x-rays?
What is longer exposure time produces more x-rays
What must be considered when adjusting exposure time in dental radiography?
What is to balance the exposure time with milliamperage
Explain how x-rays behave as they travel from their point of origin.
What is they diverge and spread out, covering a larger area
