Yes - what you must remember is that a firm's demand curve in perfect competition is its average revenue curve. Average revenue = price x quantity / quantity = price. The demand curve shows the quantity demanded at varying prices and this is exactly what the average revenue curve will do.
Because there are so many sellers in the market, no one firm has enough market power to influence price (if a firm tried to raise price consumers would move to different suppliers; nobody would buy the good), therefore price is determined by industry supply and demand, and a firm can produce any quantity at this price . This means that the firm faces a horizontal average revenue (demand curve) and if average revenue is constant, this means total revenue is increasing at a constant rate, and therefore marginal revenue is constant as well.
AnswerFor a perfectly competitive firm with no market control, the marginal revenue curve is a horizontal line. Because a perfectly competitive firm is a price taker and faces a horizontal demand curve, its marginal revenue curve is also horizontal and coincides with its average revenue (and demand) curve.

Because in Pure Competition, Demand equals Price, and Price equals Marginal Revenue;hence, Demand equals Marginal revenue.
Because monopolistically competitive firms have an optimal production allocation at monopoly values: marginal revenue = marginal cost, marking-up to the demand function. When competition is not perfect, marginal revenue does not equal demand but is always below it on a Cartesian plane, so the optimal production value of a monopolistically competitive firm is both less and at a higher price than a perfectly competitive one.
The marginal revenue curve describes the incremental change in revenue (that is, price*units sold). The MR is not always equivalent to its demand curve. The more perfect competition is, the closer demand approaches the MR. This is because, in perfect competition, firms sell at the MC = MR = P criterion. In the opposite case, monopoly, MR always lies under of demand, and firms achieve monopoly profits by choosing a production quantity where MC = MR and charging a price mark-up.
When Demand is perfectly elastic, Marginal Revenue is identical with price.
marginal revenue always lies behind the demand curve,and when demand increases marginal revenue also increases.demand curve is used to determine price of a commodity.

Price elasticity of demand is a way to determine marginal revenue. Optimal revenue and, more importantly, optimal profit will occur to the point when marginal revenue = marginal cost, or the price elasticity of demand < 1.
Profit maximization occurs when the firm produces /sets their price at the intersection of the marginal cost curve and the horizontal MR DARP curve (marginal revenue, demand, average revenue, price)
marginal revenue is negative where demand is inelastic
Under Perfect Competition the demand curve is perfectly elastic. I don't know if that helps but it might
Average Revenue (AR) is equals to Marginal Revenue (MR) in Perfect competition (PC) not imperfect competition. AR can be derived from the formula= Total revenue(TR) / Quantity. Since TR = Price x Quantity, the formula now will be Price x Quantity/ Quantity and naturally, AR equals to Price. Marginal Revenue can be measured by the formula= Change in total revenue/ Change in quantity (which is 1). Since the change in total revenue will be equals to the price of the product, MR in this case will be the Price of the product. From here we can see that Price = MR = AR = Demand.
Demand.
Average revenue (AR): total revenue per unit of a product sold; Total revenue (TR): total number of dollars received by a firm or firm from the sale of a product; Marginal revenue (MR):additional revenue received result from the sale of an extra unit of product; Under perfect competition P=AR=MR and the firm's demand curve is flat.
