A teratogen is an environmental factor that causes birth defects during prenatal development. An example of a teratogen is ionizing radiation.
teratogen
An example of infrared radiation is the heat emitted by a fire pit. An example of UV radiation is the light produced by the sun that can cause skin damage.
A teratogen is any substance or factor that can cause birth defects or developmental abnormalities in a growing fetus. These can include drugs, chemicals, infections, and other environmental factors that can negatively impact the development of the embryo or fetus during pregnancy.
The discovery itself is an example of the value of the scientific method, and has nothing to do with any aspect of electromagnetic radiation. But the confirmed existence of photons is an explanation of the particle behavior of that radiation.
For example a thermometer.

No.
The level at which a teratogen becomes harmful is referred to as the teratogenic threshold. This threshold varies depending on the type of teratogen and the stage of development of the organism. Factors such as duration of exposure and genetic susceptibility can also influence the level at which a teratogen becomes harmful.
Teratogens are anything potentially harmful to a developing fetus. These include but are not limited to: nicotine, alcohol, drugs, radiation, AIDS, rubella, etc. These cause structural abnormalities and abnormal cell masses to develop in the fetus which can lead to serious birth defects. Some examples of these are * physical and cognitive developmental delays * cleft palate * abnormal facial characteristics * mental retardation * growth defects * heart defects * abnormalities of the fingers and nails * impaired fine and gross motor skills * hearing loss * vision loss/blindness * deformed and paralyzed limbs * small head size and brain
An example of radiation is sunlight. Sunlight is a form of electromagnetic radiation that travels from the sun to Earth.
An example of infrared radiation is the heat emitted by a fire pit. An example of UV radiation is the light produced by the sun that can cause skin damage.
