1 Bushy ferns can be difficult to water. 2  Try using a watering can with a long spout to direct the water to the center of the plant. 3  Water generously, until it drains out of the bottom of the pot. 4  Bathrooms and kitchens are good environments for ferns because of all the running water.ere are a few pointers about their care: 1  Most ferns like an evenly moist soil with regular waterings. 2  Allowing the soil to dry out between waterings stresses these plants. 3  Bushy ferns can be difficult to water. 4  Try using a watering can with a long spout to direct the water to the center of the plant.
Waves traveling through a solid medium can be either transverse waves or longitudinal waves. Yet waves traveling through the bulk of a fluid (such as a liquid or a gas) are always longitudinal waves. Transverse waves require a relatively rigid medium in order to transmit their energy. As one particle begins to move it must be able to exert a pull on its nearest neighbor.
A mechanical wave requires an initial energy input. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.
