The idiom "shed light on something" comes from the literal act of illuminating something to make it visible or clearer. Historically, before the advent of electric lighting, people used candles, lanterns, or other sources of light to see in the dark. This practical need to illuminate objects and surroundings naturally extended into metaphorical use. Thus, "shedding light" on a subject came to mean providing insight or clarity, helping to understand or reveal information that was previously obscure or hidden.

Frequency refers to the number of times a wave or signal repeats in a given period, typically measured in cycles per second or Hertz (Hz). In the context of radio, television, or other electromagnetic waves, frequency determines the type of wave and its ability to carry data. For example, higher frequencies, like those in the gigahertz range, are used for things like Wi-Fi and mobile networks, while lower frequencies are often used for AM and FM radio. The frequency of a signal impacts its range, clarity, and how it interacts with the environment.

Tone in music refers to the quality or character of a sound that distinguishes it from other sounds. It encompasses aspects such as pitch, timbre, and volume. Tone helps define how a note or sound is perceived, whether it is bright, warm, harsh, or smooth. It is influenced by the instrument or voice producing the sound and how it is played or sung. Tone contributes to the overall mood and expression of the music.

Pitch refers to the degree of highness or lowness of a sound, which is determined by the frequency of the sound waves that produce it. Higher frequencies result in higher pitches, while lower frequencies produce lower pitches. For example, a whistle has a high pitch due to its rapid vibrations, whereas a bass drum produces a low pitch because of slower vibrations. Pitch plays a crucial role in music and language, as it helps convey meaning, emotion, and musical notes, contributing to the overall experience of sound.

The temporal lobe, located on the side of the brain, is involved in various functions including auditory processing, memory consolidation, language comprehension, and emotional responses. It plays a key role in interpreting sounds, understanding spoken language, and forming new memories. Additionally, the temporal lobe contributes to the recognition of faces and the perception of visual stimuli.

Modality in linguistics refers to the way speakers express attitudes, possibilities, necessities, or obligations regarding an action or situation. It is often conveyed through modal verbs such as "can," "must," or "should." For example, "She can go" expresses possibility, while "She must go" indicates necessity. Modality allows speakers to communicate their stance on the likelihood, desirability, or obligation of events, adding layers of meaning to sentences. It is essential in shaping how actions or situations are understood, giving flexibility and nuance to language.

Elementary school refers to the first stage of formal education, typically covering grades 1 through 5 or 6, depending on the country. It provides a foundational education for children, usually between the ages of 6 and 11. During this period, students learn core subjects such as reading, writing, mathematics, science, and social studies. Elementary school focuses not only on academic knowledge but also on developing social skills, emotional growth, and basic problem-solving abilities. It is the beginning of the school system, designed to prepare children for higher levels of education in middle and high schools.
