depends on the metals and the frequency
your microwave has metal screen on it that you can look thru
the wave guide in the top of the tube in the back may may be a screen only with bigger holes light is higher frequency than microwaves so can see thru smaller holes the tube where the power enters the wave guide may be a solid metal piece but the right size to be transparent
the stuff you put in the microwave may or may not get hot due to its transparency to microwave frequencies
pigments are transparent to different frequencies so your sharpie can be in different colors
TiO2 is opaque to most light light frequencies so it a handy thing to call white pigment
if you make a telescope for looking thru you can use Al or Ag for the mirror
for an IR telescope you cant use Ag its transparent this is sometimes called a cold mirror comes in handy with a microscope if you want to get enough light to see them little guys and not enough IR to boil them

What do you have to ring to ring heart FM?
That's a tricky one to answer, as Heart FM is not a single radio station, but a network of 17 local radio stations covering Central and Southern England as well as North Wales. All but one of them are owned and operated by Global Radio, with one, Heart Hertfordshire, operated as an independent franchise. It largely depends upon which one of them you want to contact- your best bet is to Google Heart FM for the area you have in mind and see if that can provide contact details. Alternatively, Global Radio has it's own page on Wikipedia, so you could try making contact through them.
What is radio wave communication?
When an electrical field changes sign, some of the energy will radiate into space. When the sign reverses the field will change again. Thus radiated into space at approx the speed of light will be a series of electromagnetic waves. These waves can also carry modulation - a characteristic of the wave may be varied. In the simplest form, the amplitude of the radio wave (commonly known as the carrier) may be varied by applying a speech signal for example. Several other modulation styles are also available, and I'll just name them, rather than describing them. Phase Modulation, Frequency Modulation, Pulse Modulation. In addition, the polarization of a wave may be varied.
What are the advantages and disanvantages of using the radio?
RadioAdvantagesA universal medium. Can be enjoyed at home, at work, and while driving. Most people listen to the radio at one time or another during the day.Permits you to target your advertising dollars to the market most likely to respond to your offer.Permits you to create a personality for your business using only sounds and voices.Free creative help is ususally available.Rates can generally be negotiated.Least inflated medium. During the past ten years, radio rates have gone up less than other media.DisadvantagesBecause radio listeners are spread over many stations, to totally saturate your market you have to advertise simultaneously on many stations.Listeners cannot refer back to your ads to go over important points.Ads are an interruption to the entertainment. Because of this, radio ads must be repeated to break through the listener's "tune out" factor.Radio is a background medium. Most listeners are doing something else while listening, which means your ad has to work hard to be listened to and understood.Advertising costs are based on ratings which are approximations based on diaries kept in a relatively small fraction of a region's homes.
How much is a victor r-15 radio worth?
Based upon eBay and the antique radio catalogs, a restored model in good working condition is worth from $200-275. I have purchased non-working, but complete, ones for $50
Does the Death Metal band Nile sing about Coptic christians in any of their songs?
All of the songs that Nile make are based upon Egyptian mythology and history.

Is infraredwaves of blood circulatory massager harmful to body?
No, because the infrared waves turn into heat waves upon contact and penetration into the body in a process called conversion.
Which metal burns in air?
Sodium, Potassium, and Phosphorus all burn upon contact with air.
How can you find songs by the original New Song group?
Call the radio station upon which you hear their music. Ask for the name of their label, and contact them.
What is wavelength vs absorbance?
Absorbance refers to the extent to which a sample absorbs light depends strongly upon the wavelength of light while wavelength refers to the Forms of electromagnetic radiation like radio waves, light waves or infrared (heat) waves make characteristic patterns as they travel through space

I need another way of saying waves crashing in the shore?
The waves pounding against the shoreline. The waves colliding with the shore. The waves breaking upon the beach.
How does land heat up?
Land heats up when waves of energy from the sun produce heat upon contact with the land's surface.
What is propogation delay in satellite?
A propagation delay is the amount of time it takes radio waves to travel from the surface of the Earth to the satellite and then back down to the Earth. The calculation of the delay is based upon the altitude and position of the satellite systems.
What mnemonics can you use to remember the electromagnetic spectrum?
Remind me if volleyball usage excites grandma. Rate my image: vote ugly, exceptional, goofy. Referees might itch violently upon examination of goals. (Radio microwave infrared visible ultraviolet X-ray gamma)

Are progressive water waves or stationary water waves produced in a ripple tank?
Both types can be produced depending upon the way that the waves are created; their height and their frequency.
