These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.

A poster is any piece of printed paper designed to be attached to a wall or vertical surface. Typically posters include both textual and graphic
elements, although a poster may be either wholly graphical or wholly
text. Posters are designed to be both eye-catching and informative.

Posters are also used for reproductions of artwork, particularly famous works, and are generally low-cost compared to original artwork.

A newspaper is a scheduled publication containing news
of current events, informative articles, diverse features, editorials,
and advertising. It usually is printed on relatively inexpensive,
low-grade paper such as newsprint.
By 2007, there were 6,580 daily newspapers in the world selling 395
million copies a day. The worldwide recession of 2008, combined with
the rapid growth of web-based alternatives, caused a serious decline in
advertising and circulation, as many papers closed or sharply
retrenched operations.

communication system whose most basic function is to allow two people
separated by large distances to talk to each other. Developed in the
mid-1870s by Alexander Graham Bell
and others, the telephone has long been considered indispensable to
businesses, households and governments, is now one of the most common appliances in the developed world. The word "telephone" has been adapted to many languages and is now recognized around the world.

Painting is the practice of applying paint, pigment, color or other medium to a surface (support base). The medium is commonly applied to the base with a brush but other implements, such as knives, sponges, and airbrushes, can be used. In art,
the term painting describes both the act and the result of the action.
However, painting is also used outside of art as a common trade among
craftsmen and builders. Paintings may have for their support such
surfaces as walls, paper, canvas, wood, glass, lacquer, clay, leaf, copper or concrete, and may incorporate multiple other materials including sand, clay, paper, gold leaf as well as objects.

A photograph or photo is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic image such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens
to focus the scene's visible wavelengths of light into a reproduction
of what the human eye would see. The process and practice of creating
photographs is called photography.
