If you could include more information you could get a more reliable answer, for example what story this is about.
Answer:
Compared with human vision, these snakes can sense electromagnetic waves that have:
3. a lower frequency and a longer wavelength.
Explanation:
Human eyes are not able to detect the infrared region of the electromagnetic spectrum. We can experience it as heat when, for instance, we get close to a hot object. <u>The snakes mentioned in the passage, however, have special sensory organs that can detect infrared, which means they sense waves that have a lower frequency and a longer wavelength than the ones visible to us. Let's compare infrared to what is detectable by human eyes:</u>
<u>Visible: wavelength: 400 nm – 700 nm; frequency: 790 THz – 430 THz.</u>
<u>Infrared: wavelength: 700 nm – 1 mm; frequency: 430 THz – 300 GHz.</u>
<u>The longer the wavelength, the lower the frequency.</u>

You use data definition language to create, modify, and delete the <u>tables, sequences, and objects</u> of a database.
Data Definition Language (DDL) is used to create and modify the shape of objects in a database using predefined instructions and a selected syntax. these database items consist of tables, sequences, locations, aliases, schemas and indexes.
Within the context of sq., data definition or data description language is a syntax for creating and editing database items together with tables, indices, and users. DDL statements are much like a computer programming language for defining data systems, particularly database schemas.
A database is an prepared collection of dependent records, or records, commonly stored electronically in a computer gadget. In computing, a database is an prepared collection of information stored and accessed electronically. Small databases may be stored on a report device, while big databases are hosted on computer clusters or cloud storage.
