Question:
A hospital uses an ultrasonic scanner to locate tumours in a tissue. What is the wavelength of sound in the tissue in which the speed of sound is 1.7 km s^-1? The operating frequency of the scanner is 4.2 MHz.

Answer:

Speed of sound in the tissue, v = 1.7 km/s = 1.7 × 10³ m/s

Operating frequency of the scanner, V = 4.2 MHz = 4.2 × 10⁶ Hz

The wavelength of sound in the tissue is given as:

λ = v / V

= 1.7 × 10³/ 4.2 × 10⁶

= 4.1 x 10^-4 m

India has had a long and unbroken tradition of great scholarship — in mathematics, astronomy, linguistics, logic and ethics. Yet, in parallel with this, several superstitious and obscurantistic attitudes and practices flourished in our society and unfortunately continue even today — among many educated people too. How will you use your knowledge of science to develop strategies to counter these attitudes ?
