1

True or false? When X-rays are being taken, barium meals are used to provide a contrast medium to show soft tissues.

1

What does a charge-coupled device (CCD) do in X-ray imaging?

1

What is the frequency of ultrasound waves?

1

True or false? If an ultrasound transducer is used to measure the length of an eyeball, this is called an I-scan.

1

Which of these formulae is used to calculate the depth of a boundary using ultrasound?

1

True or false? Snell's law states that the sine of the incident angle divided by the sine of the refractive angle is the same for each type of substance (e.g. it is the same in all glass).

1

Which way would the light ray refract if it entered a medium with a higher refractive index?

1

When will total internal reflection occur?

1

True or false? The equation connecting refractive index and critical angle is n = sin c.

1

True or false? The principal focus of a converging lens is the point from which light rays spread out.

1

True or false? The formula to calculate magnification is image height/object height.

1

Which of these statements are true about the image formed by a converging lens where the object is beyond the principal focus?

1

Which of these statements are true about the image formed by a converging lens where the object is between the lens and the principal focus?

1

Which of these statements are true about the image formed by a diverging lens?

1

Which part of the eye is light focused on?

1

Which part of the eye adjusts the thickness of the eye lens?

1

True or false? The range of vision is the distance between the near point and the far point; for the human eye, this is between 25cm and infinity.

1

What is the unit of power of a lens?

1

Which of these statements are true about myopia (short sight)?

1

Which of these statements are true about hyperopia (long sight)?
