Consider a focused 1-cm-diameter transducer with 50% bandwidth
in water. Its focal length is 2
cm. Along the transducer axis, there are two point scatters
separated by 0.25 mm axially. Find
the minimal central frequency of the transducer so that two
scatters will appear in the
ultrasound image?

Consider a focused transducer with a radius of curvature of 10 cm and a diameter of 4 cm. This transducer operates at a frequency of 3.5 MHz, and transmits a pulse of duration 0.857 μs. What is the axial resolution, in mm, at the focal point of the transducer? If the axial resolution was to be improved by a factor-of-two for example, what physical or operating parameters could be changed? Explain.

Experiment 22: The Compound Microscope f2 Object 2 1 (Objective Lens)d L, (Eyepiece) d#150mm The Compound Microscope A compound microscope uses two lenses to provide greater magnification of near objects than is possible using a single lens as a magnifier. The setup is shown above. The objective lens, L1, functions as a projector. The object is placed just beyond the focal point of L1 so a real, magnified, inverted image is formed. The eyepiece, L2, functions as a magnifier. It...
