Explanation:
1) Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nm, or 4.00 × 10⁻⁷ to 7.00 × 10⁻⁷ m, between the infrared and the ultraviolet.
2) Light travels in a straight line. This is called rectilinear propagation of light. Activity: This means that we cannot bend the ray of light to travel through the bent straw. Thus, this activity proves that light travels in a straight line.
3) the throwing back by a body or surface of light, heat, or sound without absorbing it.
4) An image is a visual representation of something. 1) An image is a picture that has been created or copied and stored in electronic form. An image can be described in terms of vector graphics or raster graphics. An image stored in raster form is sometimes called a bitmap.
