Which of the following types of electromagnetic radiation has the shortest frequency

infrared waves

microwaves

ultraviolet waves

x-rays

Microwaves has the shortest frequency.

Explanation:

In an electromagnetic spectrum, the different waves are arranged in an increasing or decreasing order of wavelength or frequency. Frequency of a wave is defined as the number of oscillations or vibrations produced. We have to write the name of wave having shortest frequency.

Frequency of infrared wave,

Frequency of microwaves wave,

Frequency of ultraviolet waves,

Frequency of x-rays,

So, from the above data it is clear that the microwaves has the shortest frequency.

Hence, the correct option is (b) " microwaves ".

answer: 4

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
