38 cards
Card 1
Question: What is a concave mirror?
Answer: A type of spherical mirror where the reflective surface curves inward, like the inside of a spoon.
Card 2
Question: Why are concave mirrors also known as converging mirrors?
Answer: Because they cause parallel rays of light to converge at a single point after reflection.
Card 3
Question: What is the Pole (P) in a concave mirror?
Answer: The geometric center of the spherical mirror's reflecting surface, where the principal axis intersects the mirror.
Card 4
Question: What is the Center of Curvature (C) for a concave mirror?
Answer: The center of the sphere from which the mirror is a part, where all points on the mirror's surface are equidistant from it.
Card 5
Question: Define the Radius of Curvature (R) for a concave mirror.
Answer: The distance between the pole (P) and the center of curvature (C), which is the radius of the sphere from which the mirror is cut.
Card 6
Question: What is the Principal Axis of a concave mirror?
Answer: An imaginary straight line passing through the pole (P) and the center of curvature (C) of the mirror, perpendicular to the mirror's surface at the po
Card 7
Question: What is the Focal Point (F) of a concave mirror?
Answer: A specific point on the principal axis where all parallel rays of light, incident on the mirror and parallel to the principal axis, converge after ref
Card 8
Question: What is the Focal Length (f) of a concave mirror?
Answer: The distance between the pole (P) and the focal point (F).
Card 9
Question: What is the relationship between the focal length (f) and the radius of curvature (R) for spherical mirrors?
Answer: f = R / 2
Card 10
Question: What happens to a ray of light traveling parallel to the principal axis after reflection from a concave mirror?
Answer: It passes through the focal point (F).
