Grade 10 Science and Other Subjects Review

These flashcards cover key concepts from the Grade 10 lecture notes in various subjects including science, mathematics, Filipino, social studies, and English.

What is Wavelength (λ)?

Wavelength (λ) is the distance between successive crests or troughs of a wave.

What is the relationship between Energy (E), Frequency (f), and Wavelength (λ)?

Energy (E) of a wave is directly related to frequency (E ∝ f); as frequency increases, wavelength decreases and energy increases.

What are Transverse waves?

Transverse waves are made of oscillating electric and magnetic fields perpendicular to each other and to the direction of propagation.

What is the speed of electromagnetic waves in a vacuum?

Electromagnetic waves travel at the speed of light, approximately 3.0 × 10⁸ m/s in a vacuum.

What are the different regions of the Electromagnetic Spectrum from lowest to highest energy?

Radio waves, Microwaves, Infrared, Visible light, Ultraviolet, X-rays, Gamma rays.

What is the effect of Ionizing radiation?

Ionizing radiation can remove electrons from atoms, potentially causing damage to cells and DNA.

What is a Convex lens?

A convex lens is a converging lens that can produce real/inverted or virtual/upright images depending on the object distance.

What are the key features of a Plane mirror?

Plane mirrors produce virtual, upright, and same-sized images; the image appears behind the mirror at the same distance as the object in front.

What is the principle behind an Electric Motor?

An Electric Motor converts electrical energy to mechanical energy based on the Lorentz force acting on a current-carrying conductor in a magnetic field.

What is the purpose of a research study?

To inform and explain facts or findings, typically with a formal tone and organized structure.

What characterizes an Argumentative text?

An argumentative text aims to convince the reader to accept the writer’s point of view through reasoned arguments and logical structure.

What is a prepared speech?

A prepared speech is written and practiced in advance, presenting clear structure and content.

What does Multimodal text involve?

A multimodal text combines two or more modes of communication, such as linguistic, visual, audio, gestural, spatial, print, and digital.

What are the main points of Globalization as discussed in the notes?

Globalization is defined as the rapid flow of people, goods, information, and products across the globe and can occur in economic, technological, socio-cultural, and political forms.

What factors contribute to issues faced by Filipino workers?

Factors include contract labor schemes, job mismatch, underemployment, and exploitation in various sectors such as agriculture, industry, and services.

What is the significance of the concept of a Circle in mathematics?

A circle is a closed curve with all points equidistant from a fixed center, described by its parts including center, arc, diameter, radius, and defining angles.

What is the primary goal of advocating for an issue?

To promote beliefs or stands on issues and inspire unity and awareness among the audience.
