### 2) amplitude

7-Mar-08

amplitude usually mean "how much" or "how large" or "how big" or "how high". In the context of a wave it means "how tall" a wave is.

For example on your "tv" when you increase the "volume" you are increasing the "amplitude" of the sound waves that TV gies out.

This process of increasing amplitude is called amplification

### 8) condemn

1-Mar-08

To strongly disapprove. To strongly disagree. To say something is very wrong. For example a President of one country can condemn the actions that he/she doesn't approve that are taking place in another country. He/she may not have the authority to do anything directly but he/she can express strong disagreement by saying he/she would condemn such actions.

### 14) frequency

7-Mar-08

Frequency is a term used to describe waves in nature. There are waves in an ocean. Then there are sound waves and then there are light waves. All these waves rise and fall. Waves come and go. They don't stand still. You can see the picture below.

How quickly these waves come one after the other is called frequency. The more waves you see in a given amount of time, say in 1 minute or in 1 hour, then "more" is their frequency. So a frequency is the number of waves you see in 1 sec.

If you have a stop watch and you are standing in the sea you can count the number of waves that hit you in 1 sec. Then that number is the frequency of waves at that time of the day.

### 15) hertz

7-Mar-08

"Hertz" is a word or more accurately a "unit" used to measure the number of waves that pass you in 1 sec, say when you stand in an ocean on a beach.

If you say 20 hertz, then you are telling someone that there are 20 waves that passed you in 1 sec. It is unlikely that the ocean waves are that frequent but sound waves can be that frequent and all the way to 20,000 hertz or 20,000 waves per sec. Light waves are billions of waves every sec and they are typically measured in Giga Hertz. A giga is a billion like a kilo is a thousand.

### 25) trestle

1-Mar-08

A criss-crossed set of legs to support something horizontal like a table or a bridge. This pattern is called a trestle.

Here is an image of a bridge supported by a trestle

### 26) wave length

7-Mar-08

How far apart two waves are, say in an ocean, is called the wave length. The farther apart they are, there is more space between them. That mean you see them that less often. So waves that are far apart will be happening less frequently. So higher wave length means low frequency. And lower wave length, or waves that are right next to each other, means higher frequency.

So a wave length and frequency are opposites and in a sense measure the same thing. How close waves are to each other.
