How does frequency affect interference?
How does frequency affect interference? A higher frequency corresponds to a shorter wavelength. Waves of shorter wavelength spread out (diffract) less after passing through the slits, and the short wavelength leads to a smaller angle at which constructive interference (one wavelength path difference between the two waves) will occur. What is interference effect? Interference, in […]
At what height the acceleration due to gravity will be reduced to 36% of its value?
At what height the acceleration due to gravity will be reduced to 36% of its value? We can write the relation between actual acceleration due to gravity and the apparent acceleration due to gravity. Hence, the height above the surface of the earth where the acceleration due to gravity is reduced by 36% of its […]
What is the rate of change on a graph?
Is biome a ecosystem?
Is biome a ecosystem? A biome is a large region of the world that has similar plants, animals and other organisms that are adapted to the terrain and weather of that region. An ecosystem is the interaction of plants and animals with nonliving things and each other. Is ecosystem bigger than community? The population, which […]
What is meant by components of velocity?
What is meant by components of velocity? Determining the Components of a Velocity Vector The two parts of a vector are known as components and describe the influence of that vector in a single direction. If a projectile is launched at an angle to the horizontal, then the initial velocity of the projectile has both […]
What is the correct classification of a mixture?
What is the correct classification of a mixture? Mixtures can be classified into two main categories: homogeneous and heterogeneous. A homogeneous mixture is one in which the composition of its constituents are uniformly mixed throughout. What is the correct classification of mixture in which both solid and liquid are visible? Whereas a solution in which […]
What type of epithelial tissue looks stratified but is not?
What type of epithelial tissue looks stratified but is not? Pseudostratified columnar epithelium is a type of epithelium that appears to be stratified but instead consists of a single layer of irregularly shaped and differently sized columnar cells. In pseudostratified epithelium, nuclei of neighboring cells appear at different levels rather than clustered in the basal […]
What is the effect of changing temperature on the pressure?
What is the effect of changing temperature on the pressure? As the temperature increases, the particles move faster, and therefore have greater speeds, so greater momentum and therefore greater force when they collide with the walls, so the pressure increases. What is the relationship between air pressure and temperature? Air pressure is influenced by temperature […]
