image you see in a mirror
The picture of a person or thing that you see in a mirror, glass, or water.
用法模式：
to see [someone]'s reflection in [something]

Learners sometimes confuse 'reflection' with 'shadow'. A reflection is an image you see in a mirror or shiny surface, while a shadow is a dark shape on a surface caused by light being blocked.
近义词

careful thought about something
When you think slowly and carefully about something, usually an important idea, choice, or experience.
用法模式：
after (some) reflection, [clause]
常见错误：
Learners sometimes use 'thinking' instead of 'reflection' in set phrases like 'after some reflection' or 'on reflection'. While 'after thinking' is understandable, 'after some reflection' sounds more natural and formal in writing and careful speech.
近义词
consideration (Sounds slightly more formal and often focuses on weighing choices, while 'reflection' can be more personal and about feelings or lessons.)
反义词
impulse (Acting on impulse means acting suddenly without reflection or careful thought.)

something that shows qualities clearly
Something that shows what a person, group, or thing is really like, often used to judge it as good or bad.
用法模式：
[something] is a [good/bad] reflection on [someone/something]
常见错误：
Learners often say 'reflection to' instead of 'reflection of' or 'reflection on'. Use 'a reflection of' to show what something is like, and 'a reflection on' to talk about how something affects a person’s or group’s reputation.
近义词
indication (A general word for a sign; 'reflection' suggests a closer, more direct connection to the quality being judged.)
反义词
misrepresentation (A misrepresentation gives a false picture, while a reflection (in this sense) is understood as accurately showing the real qualities.)

written or spoken thoughtful comments
Careful thoughts or ideas that a person writes or talks about, usually in a personal way.
用法模式：

常见错误：
Learners sometimes confuse this sense with a simple 'summary' or 'report'. A summary tells what happened; reflections explain what you think or feel about what happened and what it means.
近义词
meditations (Often more spiritual or philosophical; 'reflections' can be academic, personal, or everyday.)
反义词
report (A report focuses on facts and information, while reflections focus on personal thoughts and feelings about those facts.)

bouncing back of light or sound
When light, sound, or other waves hit a surface and then go back instead of passing through or staying in it.
用法模式：
the reflection of [light/sound] from [a surface]
常见错误：
Learners may mix 'reflection' with 'refraction'. Reflection is when waves bounce back from a surface; refraction is when waves bend as they pass into a different medium.
近义词
bounce (Informal and general; in physics, 'reflection' is the precise technical term for this 'bounce' of waves.)
反义词
absorption (Absorption happens when waves are taken in by a material instead of being reflected back.)

flipping a shape over a line
In math, a change that turns a shape into its mirror image across a line or a flat surface.
用法模式：
the reflection of [a shape] across [a line/plane]
常见错误：
Learners sometimes confuse 'reflection' with 'rotation' or 'translation'. A reflection always makes a mirror image across a line or plane, while rotation turns the shape and translation just moves it without turning.
近义词
flip (An informal classroom term for turning a shape over; 'reflection' is the precise mathematical term.)
反义词
rotation (A different geometric transformation that turns a shape without flipping it into a mirror image.)
