It is because of electro magnetic waves.take a rope and fix Its one end and pick another end and make waves on it by hand then we can see the reflection wave on it (2 dimensional). Or take a bucket full of water and drop a very small stone to it. then we can see the formation of waves and reflected waves in it (3 dimensional).
Sound waves can be reflected, refracted and even diffracted. Echo is an example of the reflection of sound waves.
The smell of grass makes a boy feel that spring is the best season. (APEX)
Question,prediction,investigation,observation and Reflection are the major steps in the inquiry process.
A qualitative observation is used in chemistry, and is simply observing physical changes.
A qualitative observation merely indicates that the subject possesses a certain quality, for example "this water is salty". A quantitative observation takes a measurement of the quality, for example "this salty water has a concentration of 10% salt".
a non-example is an astronomer looking a the ground
Qualitative observations are those that cannot be measured mathematically or assigned a value. For example, "the sky is blue," is a qualitative observation, it has no mathematical value associated with it. Quantitative observations are those that have a mathematical value. For example, "this desk is 1 meter long" is a quantitative observation. Therefore, noting that something is bubbling is an example of a qualitative observation.
The sound of a train whistle makes a woman think of an old friend.The smell of grass makes a boy feel that spring is the best season. (APEX)
periscope is an example of total internal reflection.
Wrap up the reflection by reinforcing the initial observation
that's y i'm asking!.. :)
the reflection of light...I think
Reflection from a mirror is an example that demonstrates that reflection does not change lights frequency.

Indirect observation
"the isopod has 2 antenae" is an example of which kind of observation?
The best example of multiple reflection is KALEIDOSCOPE
A mirror
