Acoustic microscopy is a high-resolution imaging technique that utilizes sound waves to investigate the internal structures of materials and biological specimens at the microscopic level. The fundamental principle involves the propagation of ultrasonic waves, which are sound waves at frequencies typically greater than 1 MHz, through the sample being studied. Here are some key aspects of acoustic microscopy: 1. **Technology**: Acoustic microscopes use high-frequency ultrasound to produce images. A transducer generates ultrasonic waves that are transmitted through the specimen.

"Sonar" refers to a technology used for detecting and locating objects underwater by using sound waves. The term is an acronym for "Sound Navigation and Ranging." Sonar systems work by emitting sound pulses (or pings) into the water and then measuring the time it takes for the echoes to return after bouncing off objects, such as the sea floor, submarines, or schools of fish.

The Toronto Transit Commission (TTC) is committed to making its services accessible to all individuals, including those with disabilities. TTC's accessibility initiatives focus on ensuring that their transit services are usable by everyone. Here are some key aspects of TTC's accessibility measures: 1. **Accessible Vehicles**: The TTC operates low-floor buses and streetcars that allow for easier boarding for people with mobility challenges. These vehicles often come equipped with features such as priority seating and audio-visual announcements.

SV Tenacious is a tall ship operated by the Jubilee Sailing Trust (JST), a UK-based charity designed to promote sailing opportunities for people of all abilities, including those with physical disabilities. Launched in 2000, SV Tenacious is notable for being one of the few tall ships in the world specifically designed to be accessible for people with disabilities, allowing them to participate in sailing and maritime experiences alongside able-bodied crew members.

STS Lord Nelson is a tall ship and a unique vessel primarily used for sail training.
